Ubushushu kunye nokukhanya kwelanga kuya kuchaphazela ixesha lokugcinwa kwe-polyester resin engaxutywanga.Enyanisweni, nokuba i-resin ye-polyester engaxutywanga okanye ezinye ii-resin, ubushushu bokugcina bungcono kwi-25 degrees Celsius kwindawo yangoku.Ngesi siseko, ukuthoba kweqondo lobushushu, ixesha elide lokuqinisekiswa kweresin yepolyester engafakwanga;ukuphakama kweqondo lobushushu, lifutshane ixesha lokuqinisekisa.
I-resin idinga ukutywinwa kwaye igcinwe kwisitya sokuqala ukukhusela ukulahlekelwa kwe-monomer volatilization kunye nokuwa kokungcola kwangaphandle.Kwaye isiciko sombhobho wokupakisha wokugcina i-resin akufanele senziwe ngobhedu okanye i-alloy yobhedu, ngokukhethekileyo i-polyethylene, i-polyvinyl chloride kunye nezinye izivalo zetsimbi.
Ngokuqhelekileyo, kwiimeko zokushisa okuphezulu, kunqande ukukhanya kwelanga ngqo kwi-barrel yokupakisha, kodwa ixesha lokugcina liya kuchaphazeleka, kuba kwiqondo lokushisa eliphezulu, ixesha le-gel le-resin liya kufinyezwa kakhulu, ukuba liyi-resin esemgangathweni. , Nditsho Uya kuqinisa ngokuthe ngqo kwi-barrel yokupakisha.Ngoko ke, ngexesha lobushushu obuphezulu, ukuba iimeko zivuma, kukulungele ukuyigcina kwindawo yokugcina i-air-conditioning eneqondo lokushisa elingaguqukiyo lama-25 degrees Celsius.Ukuba umenzi akalungiseleli i-air-conditioned warehouse, kufuneka ahlawule ingqalelo ukunciphisa ixesha lokugcina le-resin.
Kubalulekile ukuqaphela ukuba i-resin exutywe kunye ne-styrene kufuneka iphathwe njenge-hydrocarbons ezinokutsha ukukhusela umlilo.Kufuneka kubekho ulawulo olungqongqo kakhulu lweendawo zokugcina iimpahla kunye nezityalo ezigcina olu hlobo lwe-resin, kunye nokuthintela umlilo kunye nomsebenzi wokutshisa kufuneka wenziwe ngamaxesha onke.
Imiba yokhuseleko ekufuneka ithathelwe ingqalelo ngexesha lokusetyenzwa kwe-polyester resin engafakwanga kwindawo yokusebenzela
1. I-resin, i-agent ephilisayo, kunye ne-accelerator zonke izinto ezinokutsha, ngoko ke ukuthintela umlilo kufuneka kuhlawulwe ingqalelo, kwaye kufuneka zigcinwe ngokwahlukileyo, ngaphandle koko kulula kakhulu ukubangela ukuqhuma.
2. Makungabikho kutshaya kwaye kungabikho mlilo uvulekileyo kwindawo yokusebenzela yemveliso.
3. Iworkshop yemveliso kufuneka igcine umoya owaneleyo.Kukho iindlela ezimbini zokungenisa umoya kwiworkshop, enye kukugcina ukujikeleza komoya wangaphakathi, ukuze kususwe i-styrene eguqukayo nangaliphi na ixesha.Ngenxa yokuba umphunga we-styrene uxinene kunomoya, i-styrene concentration ekufutshane nomhlaba nayo iphezulu.Ngoko ke, i-exhaust vent kwi-workshop ingcono ukuseta kufuphi nomhlaba.Enye kukusebenzisa izixhobo kunye nezixhobo zokuphelisa indawo yokusebenza.Ngokomzekelo, misela i-fan exhaust eyahlukileyo ukuze ukhuphe umphunga we-styrene ophezulu-concentration kwindawo yokusebenza, okanye ukhuphe i-flue gas ngokusebenzisa umbhobho omkhulu wokufunxa ofakwe kwi-workshop.
4. Ukuze ujongane neziganeko ezingalindelekanga, iworkshop yemveliso kufuneka ibe neendawo zokuphuma ezimbini.
5. I-resin kunye ne-accelerators eyahlukeneyo egcinwe kwi-workshop yokuvelisa akufanele ibe yinto eninzi, kungcono ukugcina ixabiso elincinci.
6. Ii-resin ezingasetyenziswanga kodwa zongezwe kunye ne-accelerator kufuneka zidluliselwe kwindawo ekhuselekileyo kwaye zigcinwe ngokwahlukileyo ukukhusela ubuninzi bobushushu ekuqokeleleni ekuqokeleleni kunye nokubangela ukuqhuma nomlilo.
7. Nje ukuba i-polyester resin engaxutywanga ivuze kwaye ibangele umlilo, iigesi ezinetyhefu ziya kukhutshwa kwinkqubo kwaye zibeke engozini impilo yabantu.Ngoko ke, amanyathelo angxamisekileyo kufuneka athathwe ukujongana nayo.
