Sidee loo soo saaraa saxan bir ah oo horay loo rinjiyeeyay?

Iyada oo si tartiib tartiib ah u kordheysa isticmaalka xaashida birta midabka midabka leh ee warshadaha dhismaha, dareenka dadku waxay sii wadaan inay kor u kacaan.

Marka loo eego tirakoobyada aan dhamaystirnayn: 2016, isticmaalka gudaha Shiinaha ee taarikada birta ah ee hore loo rinjiyeeyay waxay ahayd qiyaastii 5.8 milyan oo tan. Haddaba, sidee baa saxan bir ah oo hore loo soo saaray?
Taarikada birta ah ee midabka leh(sidoo kale loo yaqaan taarikada birta ah ee dahaarka leh iyo birta hore loo dahaadhay) ayaa lagu magacaabaa taarikada birta ee saldhigga ah (oo loo yaqaan substrates) oo lagu dahaadhay midabyo kala duwan.
Xaashiyaha birta ah ee midabka leh waa badeecad leh wareeg wax soo saar oo aad u dheer.Laga soo bilaabo duubista kulul ilaa rogid qabow, waxay leedahay dhumuc gaar ah, ballac iyo qaab, ka dibna waxa la mariyaa dahaadhid, galvanizing iyo midab si ay u sameeyaan midab midab leh.xaashi midab lehHabka wax soo saarka ee ugu muhiimsan ee cutubka midabka midabka waxaa ka mid ah: Habka ka hortagga, habka daahan, habka dubista
1. Habka daawaynta
Inta badan waa habka looga saarayo wasakhda iyo saliidaha ku xiran dusha sare ka dib marka substrate-ka la nadiifiyo;iyo in lagu sameeyo oxidation-ka isku dhafan iyo daawaynta passivation si loo sameeyo filim pretreatment ah.Filimka pretreatment waa hab wax ku ool ah si loo hagaajiyo xoogga isku xidhka u dhexeeya substrate iyo daahan.
2. Habka dahaarka
Waqtigan xaadirka ah, habka daahan ee inta badan loo isticmaalo unugyada daahan midabka ee dhirta birta waaweyn waa daahan rullaluistemadka.Daahan duuban waa in la keeno rinjiga digsiga rinjiga rullaluistemadka daahan iyada oo loo marayo rullaluistemadka suunka, iyo dhumuc gaar ah oo filim qoyan ayaa laga sameeyay rullaluistemadka daahan., Ka dibna u wareeji lakabkan filimka qoyan ee habka daahan ee dusha sare ee substrate.Iyadoo hagaajinta farqiga rullaluistuadka, cadaadiska iyo xawaaraha rullaluistemadka, dhumucda dahaarka waa la kordhin karaa ama la dhimi karaa gudaha xad gaar ah;Waxa lagu rinjiyeeyay hal dhinac ama labada dhinacba isku mar.Habkani waa mid degdeg ah wuxuuna leeyahay waxtarka wax soo saarka sare.
3. Habka dubista
Habka dubista ayaa inta badan ka shaqeeya daaweynta dahaarka dusha sare ee saxanka birta, taas oo macnaheedu yahay in daahanku maraayo polycondensation kiimikaad, polyaddition, crosslinking iyo falcelin kale oo hoos yimaada heerkul gaar ah iyo xaalado kale iyada oo loo marayo walxaha ugu muhiimsan ee samaynta filimada, caawiye. wax-samaynta filimada iyo wakiilka daaweynta.Habka loo beddelo dareeraha oo loo beddelo mid adag. Daawaynta dahaarka iyo habka dubista guud ahaan waxaa ka mid ah dubista dahaarka hoose, dubista dahaarka wanaagsan iyo nidaamka u dhigma ee gaasta qashinka.
4. habaynta danbe eebir hore loo rinjiyeeyayxaashida
Oo ay ku jiraan daabacaadda, daabacaadda, laminating iyo hababka kale ee daaweynta, wax-soo-saarka ama filimka ilaalinta ayaa sidoo kale lagu dari karaa, taas oo aan kordhinaynin oo kaliya saameynta ka-hortagga daxalka ee saxanka midabka leh, laakiin sidoo kale waxay ka ilaalisaa saxanka midabka midabka leh ee xoqidda inta lagu jiro maaraynta ama farsamaynta. .
