Omabini amaqondo obushushu kunye nokukhanya kwelanga kunokuchaphazela ixesha lokugcina izinto ezinobuqhetseba. Ngapha koko, nokuba kukungapheli i-polyester poltin okanye i-resin eqhelekileyo, amaqondo obushushu agcina ezona zilungileyo kwiqondo lokushisa lengingqi ezingama-25 degrees Celsius. Kule nto, iqondo lobushushu, ixesha elide lexesha lokuqinisekiswa kwe-polyerter engacwangciswanga; Amaqondo obushushu aphezulu, akhawuleza alime.
I-resin kufuneka itywinwe kwaye igcinwe kwisikhongozeli yantlandlolo ukuthintela ukuphulukana nobungqina obuqhelekileyo kunye nokuwa kokungcola kwamanye amazwe. Kwaye isiciko se-barrel yephakeji yokugcina i-resin engenakwenziwa ngobhedu okanye ngobhedu, kwaye kungcono ukusebenzisa i-polyethylene, i-polyvinyl chloride kunye nezinye iivenkile zensimbi.
Ngokubanzi, kwimeko yobushushu obuphezulu, kwanele ukuphepha ukukhanya kwelanga ngokuthe ngqo kwiPaki. Nangona kunjalo, ubomi besheluple busaya kuchaphazeleka, ngenxa yokuba kwiqondo lobushushu obuphezulu, ixesha lejeli le-resin liya kunqanyulwa kakhulu, kwaye ukuba i-resin iphilisiwe kakhulu kwipakethi.
Ke ngoko, ngexesha lobushushu obuphezulu, ukuba iimeko ziyavuma, kungcono ukuyigcina kwindawo yokugcina impahla yomoya eneqondo lokushisa elinama-25. Ukuba umenzi akayilungisi indawo yokugcina izinto zomoya, kufuneka inikele ingqalelo ekuthinteleni ixesha lokugcina.
Kubalulekile ukuba uqaphele ukuba i-resins ixutywe neSyrene kufuneka inyangwe njenge-hydrocarbons enokutsha ukuthintela imililo. Iindawo zokugcina izinto kunye neendibano ezigciniweyo ezikugciniselayo kufuneka zibe nolawulo olungqongqo kakhulu, kwaye zenze umsebenzi olungileyo wokuthintela umlilo kunye nokuthintela umlilo nangaliphi na ixesha.
Imicimbi yoKhuseleko ekufuneka ithathelwe ingqalelo xa kulungiswa i-upodester egxunyelweyo kwiworkshop
I-1. I-resin, iarhente yokunyanga kunye nekhawulezeni zizixhobo ezinokutsha, kwaye kufuneka kuthathelwe ingqalelo ukuThintelwa komlilo. Abanye abaphendule kunye nokubuyisa kufuneka bagcinwe ngokwahlukeneyo, kungenjalo kulula ukubangela ukuqhuma.
2. Makungabikho kutshaya kwaye akukho malangatye avulekileyo kwiworkshop yemveliso.
3. Iworkshop yemveliso kufuneka igcine umoya owaneleyo. Zimbini iintlobo zokungena koomasifundisane. Enye into yokugcina ukujikeleza komoya ngaphakathi ukuze i-volits yesyrene inokususwa nangaliphi na ixesha. Ngoba i-styrene vapor i-denser kunobukroti, uxinzelelo lwesyrene kufutshane nomhlaba nayo iphezulu. Ke ngoko, kungcono ukuseta umoya kwindawo yokusebenzela kufutshane nomhlaba. Enye into kukuhlala ekuhlaleni ingingqi yokusebenza ngoncedo lwezixhobo kunye nezixhobo. Umzekelo, i-fan eyahlukileyo eyahlukileyo isetiwe ukukhupha i-vapor ephezulu yesyrene ikhutshwe kwindawo yokusebenza, okanye irhasi yefleue idiniwe ngumbhobho we-pie gestia esetiweyo kumasifundisane.
4. Ukuze ukwazi ukujongana neminyhadala engalindelekanga, iworkshop yemveliso kufuneka ifumane ubuncinci.
5. I-resin kunye nezokhenketho ezahlukeneyo ezigcinwe kwiworkshop yemveliso akufuneki zibe kakhulu, kwaye kungcono ukugcina inani elincinci.
6. I-resins engasetyenziswanga kodwa yongezwa kunye nendawo ekhuselekileyo kufuneka idluliselwe kwindawo ekhuselekileyo yogcino, ukwenzela ukuthintela ubungakanani obukhulu bokuqokelelwa kunye nokuqokelela iziqhushumbisi kunye nemililo.
7. Nje ukuba i-polyester engadibaniyo iphinde ivule, iya kubangela umlilo, kwaye irhasi enetyhefu iya kukhutshwa kule nkqubo, eya kufikelela kwimpilo yabantu. Ke ngoko, amanyathelo kaxakeka makathathwe ukujongana nayo.
