Ubushushu kunye nokukhanya kwelanga kunokuchaphazela ixesha lokugcina ii-polyester resins ezingagcwaliyo. Enyanisweni, nokuba yi-polyester resin engagcwaliyo okanye i-resin eqhelekileyo, ubushushu bokugcina bungcono kakhulu kubushushu bengingqi bangoku obungama-25 degrees Celsius. Ngenxa yesi sizathu, okukhona ubushushu buphantsi, kokukhona ixesha lokusebenza kwe-polyester resin engagcwaliyo lide; okukhona ubushushu buphezulu, kokukhona ixesha lokusebenza lifutshane.
I-resin kufuneka ivalwe kwaye igcinwe kwisikhongozeli sokuqala ukuthintela ukulahleka kwe-monomer volatilization kunye nokuwa kokungcola okungaphandle. Kwaye isiciko sebharele yokupakisha yokugcina i-resin asinakwenziwa nge-copper okanye i-copper alloy, kwaye kungcono ukusebenzisa i-polyethylene, i-polyvinyl chloride kunye nezinye izivikelo zesinyithi.
Ngokubanzi, kwimeko yobushushu obuphezulu, kwanele ukunqanda ukukhanya kwelanga ngqo kwibharele yokupakisha. Nangona kunjalo, ixesha lokugcinwa kweshelufu liya kuchaphazeleka, kuba kwimozulu yobushushu obuphezulu, ixesha lejeli ye-resin liya kufinyezwa kakhulu, kwaye ukuba i-resin ayisemgangathweni ophantsi, iya kunyangwa ngqo kwibharele yokupakisha.
Ngoko ke, ngexesha lobushushu obuphezulu, ukuba iimeko ziyavuma, kungcono ukuyigcina kwindawo yokugcina izinto enomoya opholileyo enobushushu obungaguqukiyo obungama-25 degrees Celsius. Ukuba umenzi akayilungiseleli indawo yokugcina izinto enomoya opholileyo, kufuneka anikele ingqalelo ekunciphiseni ixesha lokugcina i-resin.

Kubalulekile ukuqaphela ukuba ii-resin ezixutywe ne-styrene maziphathwe njengee-hydrocarbon ezinokutsha ukuthintela imililo. Iindawo zokugcina impahla kunye neeworkshop ezigcina ezi resin kufuneka zibe nolawulo olungqongqo kakhulu, kwaye zenze umsebenzi olungileyo wokuthintela umlilo kunye nokuthintela umlilo nangaliphi na ixesha.

Imiba yokhuseleko ekufuneka iqwalaselwe ngexesha lokucubungula i-resin ye-polyester egcweleyo kwindawo yokusebenzela
1. I-resin, i-curing agent kunye ne-accelerator zonke zizinto ezinokutsha, kwaye kufuneka kuqwalaselwe ukuthintela umlilo. Ezinye ii-accelerator kunye nee-resin kufuneka zigcinwe ngokwahlukeneyo, kungenjalo kulula ukubangela ukuqhuma.
2. Akufuneki kubekho kutshaya kwaye kungabikho mlilo uvulekileyo kwindawo yokusebenzela yemveliso.
3. Indawo yokusebenzela yemveliso kufuneka igcine umoya owaneleyo. Kukho iindlela ezimbini zokungenisa umoya kwindawo yokusebenzela. Enye kukugcina umoya ujikeleza ngaphakathi ukuze i-volatiles ye-styrene isuswe nangaliphi na ixesha. Ngenxa yokuba umphunga we-styrene uxinene kunomoya, uxinzelelo lwe-styrene kufutshane nomhlaba nalo luphezulu. Ke ngoko, kungcono ukubeka indawo yokukhupha umoya kwindawo yokusebenzela kufutshane nomhlaba. Enye kukukhupha umoya kwindawo yokusebenza ngoncedo lwezixhobo nezixhobo. Umzekelo, ifeni eyahlukileyo yokukhupha umoya imiselwe ukukhupha umphunga we-styrene oxineneyo ophezulu okhutshwa kwindawo yokusebenza, okanye igesi yeflue ikhutshwa ngepayipi yokufunxa eqhelekileyo ebekwe kwindawo yokusebenzela.
4. Ukuze kujongwane neziganeko ezingalindelekanga, indawo yokusebenzela yemveliso kufuneka ibe neendlela ezimbini zokuphuma.
5. I-resin kunye nee-accelerators ezahlukeneyo ezigcinwe kwindawo yokusebenzela yemveliso akufuneki zibe zininzi kakhulu, kwaye kungcono ukugcina inani elincinci.

6. Iiresini ezingasetyenziswanga kodwa zongezwe ngee-accelerators kufuneka zidluliselwe kwindawo ekhuselekileyo yokugcina izinto ezisasazekileyo, ukuze kuthintelwe ukuba ubushushu obuninzi bungaqokeleli kwindawo eqokeleleneyo nto leyo ebangela ukuqhuma kunye nemililo.
7. Xa i-resin ye-polyester engagcwaliyo ivuza, iya kubangela umlilo, kwaye igesi enobuthi iya kukhutshwa ngeli xesha le nkqubo, nto leyo eya kubeka impilo yabantu esichengeni. Ke ngoko, kufuneka kuthathwe amanyathelo angxamisekileyo ukujongana nayo.
