Q1.Niyihe mpamvu yo kutagira aho ibogamiye silicone kashe ihinduka umuhondo?
Igisubizo:
Umuhondo wa silicone idafite aho ibogamiye iterwa nubusembwa buri kashe ubwayo, ahanini biterwa numusaraba uhuza kandi ukabyimbye muri kashe itabogamye. Impamvu nuko ibyo bikoresho bibiri bibisi birimo "amatsinda ya amino", byoroshye cyane kumuhondo. Benshi mu bicuruzwa bizwi cyane bya silicone bifunga ibicuruzwa nabyo bifite ibi bintu byumuhondo.
Byongeye kandi, niba kashe ya silicone idafite aho ibogamiye ikoreshwa mugihe kimwe na silicone silicone kashe, irashobora gutuma kashe idafite aho ibogamiye ihinduka umuhondo nyuma yo gukira. Irashobora kandi guterwa nigihe kirekire cyo kubika kashe cyangwa reaction hagati ya kashe na substrate.
Q2.Kuki silicone idafite aho ibogamiye ibara ryera rimwe na rimwe rihinduka ibara ryijimye? Ikidodo kimwe gisubira cyera icyumweru nyuma yo gukira?
Igisubizo:
Alkoxy yakize ubwoko bwa silicone itagira aho ibogamiye irashobora kugira iki kintu kubera umusaruro wibikoresho fatizo bya titanium chromium. Chromium ya Titanium ubwayo itukura, kandi ibara ryera rya kashe igerwaho nifu ya dioxyde de titanium muri kashe ikora nkibara.
Nyamara, kashe ni ikintu kama, kandi imiti myinshi yimiti irashobora guhinduka, hamwe nibisubizo byuruhande. Ubushyuhe nurufunguzo rwo gukurura ibyo bitekerezo. Iyo ubushyuhe buri hejuru, ibintu byiza nibibi bibaho, bigatera amabara guhinduka. Ariko nyuma yubushyuhe bumaze kugabanuka no guhagarara, reaction irahindukira kandi ibara risubira muburyo bwa mbere. Hamwe nubuhanga bwiza bwo kubyaza umusaruro no kumenya neza, ibi bintu bigomba kwirindwa.
Q3.Ni ukubera iki ibicuruzwa bimwe byo mu rugo bisobanutse bihindura ibara ryera nyuma yiminsi itanu yo gusaba? Ni ukubera iki kutagira aho bibogamiye bihindura ibara ryera nyuma yo kubisaba?
Igisubizo:
Ibi bigomba kandi kwitirirwa ikibazo cyo guhitamo ibikoresho fatizo no kugenzura. Bimwe mubicuruzwa byo mu rugo bibonerana birimo plasitike ihindagurika byoroshye, mugihe ibindi birimo ibyuzuza imbaraga. Iyo plasitike ihindagurika, kashe iragabanuka kandi irambuye, byerekana ibara ryuzuza (ibyuzuye byose muri kashe idafite aho ibogamiye byera ibara).
Ibidodo byamabara bikozwe mukongeramo pigment kugirango bibe amabara atandukanye. Niba hari ibibazo byo guhitamo pigment, ibara rya kashe irashobora guhinduka nyuma yo gusaba. Ubundi, niba ibidodo byamabara bikoreshwa muburyo bworoshye mugihe cyo kubaka, kugabanuka kwa kashe mugihe cyo gukira birashobora gutuma ibara ryoroha. Muri iki kibazo, birasabwa kugumana umubyimba runaka (hejuru ya 3mm) mugihe ushyizeho kashe.
Q4.Kuki ibibara cyangwa ibimenyetso bigaragara ku ndorerwamo nyuma yo gukoresha kashe ya silicone inyuma kuri aigihe?
Igisubizo:
Mubisanzwe hariho ubwoko butatu bwo gutwikira inyuma yindorerwamo kumasoko: mercure, ifeza yera, n'umuringa.
Mubisanzwe, nyuma yo gukoresha kashe ya silicone kugirango ushyire indorerwamo mugihe runaka, ubuso bwindorerwamo bushobora kugira ibibara. Ubusanzwe biterwa no gukoresha acic silicone kashe, ikora hamwe nibikoresho byavuzwe haruguru kandi igatera ibibanza hejuru yindorerwamo. Kubwibyo, dushimangira ikoreshwa rya kashe idafite aho ibogamiye, igabanijwemo ubwoko bubiri: alkoxy na oxime.
Niba indorerwamo ishyigikiwe n'umuringa yashizwemo na oxime idafite aho ibogamiye, oxime izonona gato ibikoresho byumuringa. Nyuma yigihe cyubwubatsi, hazashyirwaho ibimenyetso byangirika inyuma yindorerwamo aho kashe ikoreshwa. Ariko, niba alkoxy idafite aho ibogamiye ikoreshwa, iki kintu ntikizabaho.
Ibi byose byavuzwe haruguru biterwa no guhitamo ibikoresho bidakwiye biterwa nubwinshi bwa substrate. Kubwibyo, birasabwa ko abakoresha bakora ikizamini cyo guhuza mbere yo gukoresha kashe kugirango barebe niba kashe ihuye nibikoresho.
Q5.Ni ukubera iki kashe ya silicone igaragara nka granules ingana na kristu yumunyu iyo ikoreshejwe, kandi ni ukubera iki zimwe muri izo granules zishonga ubwazo nyuma yo gukira?
Igisubizo:
Iki nikibazo kijyanye nibikoresho fatizo bikoreshwa muguhitamo silicone. Ibicuruzwa bimwe na bimwe bya silicone birimo ibintu bihuza bishobora gutobora ubushyuhe buke, bigatuma umukozi uhuza imbaraga akomera imbere mumacupa yometse. Nkigisubizo, mugihe ibifatika byatanzwe, granules zimeze nkumunyu zingana nubunini butandukanye zirashobora kuboneka, ariko bizagenda bishonga buhoro buhoro mugihe, bigatuma granules ihita ibura mugihe cyo gukira. Ibi bintu ntacyo bihindura kumiterere ya silicone. Impamvu nyamukuru itera iki kibazo ningaruka zikomeye zubushyuhe buke.
Q6.Ni izihe mpamvu zishoboka zituma silicone ikorerwa mu gihugu ikoreshwa mu kirahure idashobora gukira nyuma yiminsi 7?
Igisubizo:
Ibi bintu bikunze kubaho mugihe cyubukonje.
1.Ikidodo gikoreshwa cyane, bikaviramo gukira buhoro.
2.Ibidukikije byubatswe byatewe nikirere kibi.
3.Ikidodo cyararangiye cyangwa gifite inenge.
4.Ikidodo kiroroshye cyane kandi wumva kidashobora gukira.
Q7.Niyihe mpamvu yibibyimba bigaragara mugihe ukoresheje ibicuruzwa bimwe na bimwe byakozwe mu gihugu imbere?
Igisubizo:
Hashobora kubaho impamvu eshatu zishoboka:
1.Ikoranabuhanga ribi mugihe cyo gupakira, bigatuma umwuka ufatwa mumacupa.
2.Abashoramari bake batitonda babigambiriye ntibagumane umutego wo hasi wigituba, hasigara umwuka mubitereko ariko bigatanga ibitekerezo byubunini bwa silicone ihagije.
3.Bimwe mubidodo bya silicone byimbere mu gihugu birimo ibyuzuzo bishobora kubyitwaramo neza hamwe na plastike yoroshye ya PE ya silicone ya kashe ya pisine, bigatuma umuyoboro wa plastike wabyimba kandi ukiyongera muburebure. Nkigisubizo, umwuka urashobora kwinjira mumwanya uri muri tube hanyuma ugatera icyuho muri kashe ya silicone, bikavamo amajwi yibibyimba mugihe cyo kubishyira mubikorwa. Inzira ifatika yo gutsinda iki kibazo ni ugupakira imiyoboro no kwita kububiko bwibicuruzwa (munsi ya 30 ° C ahantu hakonje).
Q8.Ni ukubera iki kashe ya silicone idafite aho ibogamiye ikoreshwa muguhuza ibyuma bya beto nicyuma ikora idirishya ryinshi nyuma yo gukira mugihe cyizuba, mugihe izindi zitabikora? Ni ikibazo cyiza? Kuki ibintu nkibi bitigeze bibaho mbere?
Igisubizo:
Ibirango byinshi bya silicone idafite aho ibogamiye yahuye nibintu bisa, ariko mubyukuri ntabwo arikibazo cyiza. Abadafite aho babogamiye baza muburyo bubiri: alkoxy na oxime. Kandi kashe ya alkoxy irekura gaze (methanol) mugihe cyo gukiza (methanol itangira guhinduka nka 50 ℃), cyane cyane iyo ihuye nizuba ryinshi cyangwa ubushyuhe bwinshi.
Byongeye kandi, idirishya ryamadirishya ya beto nicyuma ntabwo byinjira cyane mukirere, kandi mugihe cyizuba, hamwe nubushyuhe bwinshi nubushuhe, kashe ikira vuba. Gazi isohoka muri kashe irashobora guhunga gusa igice cyakize igice cya kashe, bigatuma ibibyimba bifite ubunini butandukanye bigaragara kuri kashe yakize. Nyamara, okisime idafite aho ibogamiye ntishobora kurekura gaze mugihe cyo gukira, ntabwo rero itanga ibibyimba.
Ariko imbogamizi ya silicone itagira aho ibogamiye ni uko niba ikoranabuhanga no kuyikora bidakozwe neza, birashobora kugabanuka no gucika mugihe cyo gukira mugihe cyubukonje.
Mu bihe byashize, ibintu nk'ibi ntibyigeze bibaho kubera ko kashe ya silicone yakoreshwaga gake ahantu nk'aha n'ubwubatsi, kandi ibikoresho byo gufunga amazi bita acrylic byakoreshwaga mu mwanya wabyo. Kubwibyo, ibintu byo kubyimba muri silicone idafite aho ibogamiye ntibyari bisanzwe. Mu myaka yashize, ikoreshwa rya kashe ya silicone ryagiye ryamamara buhoro buhoro, rizamura cyane urwego rw’ubwubatsi, ariko kubera kutumva neza ibintu biranga ibintu, guhitamo ibikoresho bidakwiye byatumye habaho ibintu byinshi byo gufunga kashe.
Q9.Nigute ushobora gukora ibizamini byo guhuza?
Igisubizo:
Mu magambo make, igeragezwa ryuzuzanya hagati yifatizo hamwe ninyubako zubaka bigomba gukorwa nishami rishinzwe gupima ibikoresho byigihugu byemewe. Ariko, birashobora gufata igihe kirekire kandi birahenze kubona ibisubizo binyuze muri aya mashami.
Ku mishinga isaba ibizamini nkibi, birakenewe kubona raporo yubugenzuzi bujuje ibisabwa n’ikigo cy’igihugu gishinzwe ibizamini byemewe mbere yo gufata icyemezo cyo gukoresha ibicuruzwa byubaka. Kubikorwa rusange, substrate irashobora gutangwa kubakora silicone kashe yo gukora ibizamini. Ibisubizo byo kwipimisha birashobora kuboneka muminsi igera kuri 45 kububiko bwa silicone yubatswe, niminsi 35 kubutaka bwa silicone butabogamye.
Q10.Ni ukubera iki kashe ya silicone ya silicone ikuramo byoroshye kuri sima?
Igisubizo: Kashe ya silicone ya silike itanga aside mugihe cyo gukira, ifata hejuru yibikoresho bya alkaline nka sima, marble, na granite, bigakora ibintu bya chalky bigabanya gufatana hagati yifata na substrate, bigatuma kashe ya acide ihita yikuramo byoroshye. kuri sima. Kugira ngo wirinde iki kibazo, birakenewe gukoresha ibidafite aho bibogamiye cyangwa oxyde ikwiranye na alkaline substrate yo gufunga no guhuza.
