Kokubili izinga lokushisa nokukhanya kwelanga kungathinta isikhathi sokugcinwa kwama-polyester resins angagcwele.Eqinisweni, kungakhathaliseki ukuthi i-polyester resin engagcwele noma i-resin evamile, izinga lokushisa lokugcina lingcono kakhulu ekushiseni kwamanje kwesifunda okungu-25 degrees Celsius.Ngalesi sisekelo, ukwehla kwezinga lokushisa, isikhathi sokufaneleka se-polyester resin engagcwele;lapho izinga lokushisa liphezulu, isikhathi sokuqinisekisa siba sifushane.
I-resin idinga ukuvalwa futhi igcinwe esitsheni sokuqala ukuvimbela ukulahleka kokushintshashintsha kwe-monomer kanye nokuwa kokungcola kwamanye amazwe.Futhi isembozo somgqomo wokupakisha wokugcina i-resin asikwazi ukwenziwa ngethusi noma i-alloy yethusi, futhi kungcono ukusebenzisa i-polyethylene, i-polyvinyl chloride nezinye izivalo zensimbi.
Ngokuvamile, esimweni sokushisa okuphezulu, kwanele ukugwema ukukhanya kwelanga ngqo emgqonyeni wokupakisha.Kodwa-ke, impilo yeshalofu isazothinteka, ngoba esimweni sezulu esishisayo, isikhathi se-gel se-resin sizofushaniswa kakhulu, futhi uma i-resin isezingeni eliphansi, izophulukiswa ngokuqondile emgqonyeni wokupakisha.
Ngakho-ke, ngesikhathi sokushisa okuphezulu, uma izimo zivuma, kungcono ukuyibeka endaweni yokugcina impahla ene-air conditioning enezinga lokushisa elingaguquki lama-25 degrees Celsius.Uma umkhiqizi engalungiseleli indawo yokugcina impahla ene-air conditioning, kufanele inake ukunciphisa isikhathi sokugcina se-resin.

Kubalulekile ukuqaphela ukuthi ama-resin ahlanganiswe ne-styrene kufanele aphathwe njengama-hydrocarbons avuthayo ukuvimbela umlilo.Izindlu zokugcina impahla kanye nezindawo zokusebenzela ezigcina lezi zinsalela kumele zibe nokuphathwa okuqinile, futhi zenze umsebenzi omuhle wokuvikela umlilo nokuvikela umlilo nganoma yisiphi isikhathi.

Izindaba zokuphepha okufanele zinakwe ngesikhathi sokucutshungulwa kwe-polyester resin egcwele endaweni yokusebenzela
1. I-resin, i-ejenti yokwelapha kanye ne-accelerator zonke izinto ezivuthayo, futhi kufanele kuqashelwe ukuvimbela umlilo.Amanye ama-accelerator nama-resin kufanele agcinwe ngokuhlukana, ngaphandle kwalokho kulula ukubangela ukuqhuma.
2. Akumele kube khona ugwayi futhi kungabikho amalangabi avulekile endaweni yokusebenzela yokukhiqiza.
3. Indawo yokusebenzela yokukhiqiza kufanele igcine umoya owanele.Kunezinhlobo ezimbili zokungenisa umoya endaweni yokusebenzela.Enye iwukugcina ukujikeleza komoya wasendlini ukuze ama-volatiles e-styrene asuswe nganoma yisiphi isikhathi.Ngenxa yokuthi umhwamuko we-styrene uminyene kunomoya, ukuhlangana kwe-styrene eduze nomhlabathi nakho kuphakeme kakhulu.Ngakho-ke, kungcono kakhulu ukusetha indawo yokukhipha umoya endaweni yokusebenzela eduze nomhlabathi.Okunye ukuqeda indawo yokusebenza ngosizo lwamathuluzi nemishini.Isibonelo, ifeni yokukhipha umoya ehlukile iyasethwa ukuze kukhishwe umhwamuko we-styrene wokugxila okuphezulu okhishwa endaweni yokusebenza, noma igesi ephumayo iyaphela ngepayipi elivamile lokumunca elibekwe endaweni yokusebenzela.
4. Ukuze ubhekane nezigigaba ezingalindelekile, ishabhu yokukhiqiza kumele okungenani ibe nezindawo zokuphuma ezimbili.
5. I-resin kanye nama-accelerator ahlukahlukene agcinwe ku-workshop yokukhiqiza akufanele abe kakhulu, futhi kungcono ukugcina inani elincane.

6. Ama-resin angazange asetshenziswe kodwa afakwe nama-accelerator kufanele adluliselwe endaweni ephephile ukuze agcinwe endaweni ehlakazekile, ukuze avimbele ukushisa okukhulu ekuqoqeni futhi kubangele ukuqhuma nemililo.
7. Uma i-polyester resin engasetshenzisiwe ivuza, izodala umlilo, futhi igesi enobuthi izokhishwa phakathi nale nqubo, ezobeka impilo yomuntu engozini.Ngakho-ke, izinyathelo eziphuthumayo kufanele zithathwe ukubhekana nakho.
