Kokubili izinga lokushisa kanye nokukhanya kwelanga kungathinta isikhathi sokugcina ama-resin e-polyester angagcwali. Eqinisweni, kungakhathaliseki ukuthi yi-resin ye-polyester engagcwali noma i-resin evamile, izinga lokushisa lokugcina lingcono kakhulu ekushiseni kwesifunda samanje okungama-degree Celsius angama-25. Ngalesi sisekelo, lapho izinga lokushisa liphansi, isikhathi sokusebenza se-resin ye-polyester engagcwali siba side; lapho izinga lokushisa liphakama, isikhathi sokusebenza siba sifushane.
I-resin idinga ukuvalwa futhi igcinwe esitsheni sokuqala ukuvimbela ukulahlekelwa yi-monomer volatilization kanye nokuwa kokungcola kwangaphandle. Futhi isembozo sebhakede lokupakisha lokugcina i-resin asinakwenziwa ngethusi noma i-alloy yethusi, futhi kungcono ukusebenzisa i-polyethylene, i-polyvinyl chloride nezinye izivalo zensimbi.
Ngokuvamile, uma kwenzeka izinga lokushisa eliphezulu, kwanele ukugwema ukukhanya kwelanga okuqondile emgqonyeni wokupakisha. Kodwa-ke, isikhathi sokuphelelwa yisikhathi sizoqhubeka sithinteke, ngoba esimweni sezulu esishisayo kakhulu, isikhathi sejeli se-resin sizofinyezwa kakhulu, futhi uma i-resin ingekhwalithi embi, izophiliswa ngqo emgqonyeni wokupakisha.
Ngakho-ke, ngesikhathi sokushisa okuphezulu, uma izimo zivuma, kungcono ukuyigcina endaweni yokugcina izinto enomoya opholile enezinga lokushisa elingaguquki elingu-25 degrees Celsius. Uma umenzi engalungiseleli indawo yokugcina izinto enomoya opholile, kumele aqaphele ukunciphisa isikhathi sokugcina i-resin.

Kubalulekile ukuqaphela ukuthi ama-resin axutshwe ne-styrene kumele aphathwe njengama-hydrocarbon avuthayo ukuze kuvinjelwe imililo. Izindawo zokugcina impahla kanye nama-workshop agcina la ma-resin kumele abe nokuphathwa okuqinile, futhi enze umsebenzi omuhle wokuvimbela umlilo kanye nokuvimbela umlilo nganoma yisiphi isikhathi.

Izindaba zokuphepha okumele ziqashelwe ngesikhathi kucutshungulwa i-resin egcwele i-polyester eshabhu
1. I-resin, i-curing agent kanye ne-accelerator konke kuyizinto ezivuthayo, futhi kufanele kuqashelwe ukuvimbela umlilo. Amanye ama-accelerator nama-resin kumele agcinwe ngokwehlukana, ngaphandle kwalokho kulula ukubangela ukuqhuma.
2. Akufanele kube khona ukubhema futhi kungabikho amalangabi avulekile endaweni yokukhiqiza.
3. Indawo yokukhiqiza kumele igcine umoya owanele. Kunezinhlobo ezimbili zomoya ophumayo endaweni yokusebenzela. Enye iwukugcina umoya ujikeleza ngaphakathi ukuze ukuguquguquka kwe-styrene kususwe nganoma yisiphi isikhathi. Ngenxa yokuthi umusi we-styrene uminyene kunomoya, ukugcwala kwe-styrene eduze komhlabathi nakho kuphakeme kakhulu. Ngakho-ke, kungcono ukubeka indawo yokukhipha umoya endaweni yokusebenzela eduze nomhlaba. Enye iwukukhipha umoya endaweni yokusebenza ngosizo lwamathuluzi nemishini. Isibonelo, kufakwa ifeni ehlukile yokukhipha umoya ukuze kukhishwe umoya we-styrene ophuma endaweni yokusebenza, noma igesi yomoya ikhishwa ngepayipi elijwayelekile lokudonsa elisethelwe endaweni yokusebenzela.
4. Ukuze kuxazululwe izenzakalo ezingalindelekile, indawo yokukhiqiza kumele okungenani ibe nezindawo ezimbili zokuphuma.
5. I-resin kanye nezisheshisi ezahlukahlukene ezigcinwe endaweni yokukhiqiza akufanele zibe ziningi kakhulu, futhi kungcono ukugcina inani elincane.

6. Ama-resin angasetshenziswanga kodwa anezelwe ngama-accelerator kufanele adluliselwe endaweni ephephile yokugcina izinto ezihlakazekile, ukuze kuvinjelwe ukushisa okukhulu ukuthi kunganqwabelani ekuqongeleleni bese kubangele ukuqhuma nemililo.
7. Uma i-resin ye-polyester engagcwali ivuza, izobangela umlilo, futhi igesi enobuthi izokhishwa phakathi nale nqubo, okuzobeka impilo yabantu engozini. Ngakho-ke, kumele kuthathwe izinyathelo eziphuthumayo ukubhekana nayo.
