Ubushushu kunye nokukhanya kwelanga kuya kuchaphazela ixesha lokugcina i-polyester resin engagcwaliyo. Enyanisweni, nokuba yi-polyester resin engagcwaliyo okanye ezinye ii-resin, ubushushu bokugcina bungcono ngama-25 degrees Celsius kwindawo yangoku. Ngenxa yesi sizathu, okukhona ubushushu buphantsi, kokukhona ixesha lokusebenza le-polyester resin engagcwaliyo lide; okukhona ubushushu buphezulu, kokukhona ixesha lokusebenza lifutshane.
I-resin kufuneka ivalwe ize igcinwe kwisikhongozeli sokuqala ukuthintela ukulahleka kwe-monomer volatilization kunye nokuwa kokungcola kwangaphandle. Kwaye isiciko sebharele yokupakisha yokugcina i-resin akufuneki senziwe nge-copper okanye i-copper alloy, kungcono i-polyethylene, i-polyvinyl chloride kunye nezinye izivikelo zesinyithi.
Ngokubanzi, kwiimeko zobushushu obuphezulu, thintela ukukhanya kwelanga ngqo kwibhareli yokupakisha, kodwa ixesha lokugcina liza kuchaphazeleka, kuba kwimozulu yobushushu obuphezulu, ixesha lejeli le-resin liya kufinyezwa kakhulu, ukuba yi-resin ekumgangatho ophantsi, nokuba iya kuqina ngqo kwibhareli yokupakisha. Ke ngoko, ngexesha lobushushu obuphezulu, ukuba iimeko ziyavuma, kungcono ukuyigcina kwindawo yokugcina enomoya opholileyo enobushushu obungaguqukiyo obungama-25 degrees Celsius. Ukuba umenzi akayilungiseleli indawo yokugcina enomoya opholileyo, kufuneka anikele ingqalelo ekufinyezeni ixesha lokugcina le-resin.
Kubalulekile ukuqaphela ukuba i-resin exutywe ne-styrene kufuneka iphathwe njengee-hydrocarbon ezinokutsha ukuthintela umlilo. Kufuneka kubekho ulawulo olungqongqo kakhulu kwiindawo zokugcina impahla kunye nezityalo ezigcina olu hlobo lwe-resin, kwaye umsebenzi wokuthintela umlilo kunye nokutshisa kufuneka wenziwe ngamaxesha onke.
Imiba yokhuseleko ekufuneka iqwalaselwe ngexesha lokucubungula i-resin ye-polyester engagcwaliyo kwindawo yokusebenzela
1. I-resin, i-anti-curing agent, kunye ne-accelerator zonke zizinto ezinokutsha, ngoko ke ukuthintela umlilo kufuneka kunikwe ingqalelo, kwaye kufuneka zigcinwe ngokwahlukeneyo, kungenjalo kulula kakhulu 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 kususwe i-styrene eguquguqukayo nangaliphi na ixesha. Ngenxa yokuba umphunga we-styrene uxinene kunomoya, uxinzelelo lwe-styrene kufutshane nomhlaba nalo luphezulu. Ke ngoko, umoya wokukhupha umoya kwindawo yokusebenzela kungcono ubekwe kufutshane nomhlaba. Enye kukusebenzisa izixhobo kunye nezixhobo zokukhupha umoya kwindawo yokusebenza. Umzekelo, misela ifeni eyahlukileyo yokukhupha umoya ukuze ukhuphe umphunga we-styrene oxineneyo ophezulu kwindawo yokusebenza, okanye ukhuphe igesi yeflue ngepayipi ephambili yokufunxa efakwe 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, kungcono ukugcina inani elincinci.
6. Iiresini ezingasetyenziswanga kodwa zongezwe ngee-accelerators kufuneka zidluliselwe kwindawo ekhuselekileyo kwaye zigcinwe ngokwahlukeneyo ukuthintela ukuba ubushushu obukhulu buqokeleleke kwindawo eqokeleleneyo nto leyo ebangela ukuqhuma nomlilo.
7. Xa i-resin ye-polyester engagcwaliyo ivuza ize ibangele umlilo, iigesi ezinobuthi ziya kukhutshwa ngexesha lenkqubo kwaye zibeke impilo yabantu esichengeni. Ke ngoko, kufuneka kuthathwe amanyathelo angxamisekileyo ukujongana nayo.
