1, Cacisa izimo zohlelo lokusebenza kanye nezidingo zokusebenza
1. Ukudla/Imikhiqizo Yezokwelapha
Beka phambili ukusetshenziswa kwezithambisi ze-organotin (i-mercaptan methyl tin), ezihlangabezana nezindinganiso ze-FDA futhi ezinokubonakala okuphezulu, ezifanele imikhiqizo ye-PVC esobala, amafilimu okupakisha ukudla, njll.; Ezinye izinketho zifaka phakathi izithambisi ze-calcium zinc composite, okumele ziqinisekiswe yi-REACH, i-LFGB, kanye nezinye izindinganiso ukuze kuhlangatshezwane nezidingo zokufuduka okungenabo ubuthi.
2. Izinto zokwakha/zezimboni
Amapayipi namapuleti aqinile: Kunconywa ukusebenzisa iziqinisi ezihlanganisiwe zosawoti we-lead (ezingabizi kakhulu, eziqinile ekushiseni okuphezulu), kodwa kufanele kuqashelwe imikhawulo yazo emvelweni.
2, Hlola imithethonqubo yezemvelo nezokuphepha
1. Ukuthobela imithetho yezemvelo:
Kudingeka izinto zokuqinisa ezingenayo i-lead kanye ne-cadmium ezifana ne-calcium zinc composite noma i-organotin stabilizer ukuze zithunyelwe e-European Union noma emikhakheni yezokwelapha.
Gwema izinto eziqinisa usawoti we-lead (ubuthi obuphezulu) bese ukhetha imikhiqizo ehambisana nezindinganiso ze-ROHS kanye ne-REACH.
2. Ukuphepha kokuthintana: Izinga lokufuduka kweziqinisi kufanele liqinisekiswe ngezinto zokupakisha ukudla, futhi amafomula ahlanganisiwe anesisindo esikhulu sama-molecule kufanele akhethwe.
3, ubuchwepheshe bokucubungula ukufanisa kanye nohlelo lokugcoba
1. Ukuzivumelanisa nezindlela zokucubungula
Ukubumba kokukhipha/ukufaka umjovo: Iziqinisi ze-tin eziphilayo zidinga ukuhlanganiswa nohlelo lokugcoba lwe-paraffin wax+calcium stearate, futhi inani lokugcoba kwangaphandle elingeziwe kufanele lilawulwe ezingxenyeni ezingu-0.1-0.5 ukuze kugwenywe ukuhlakazeka okungalingani;
Ukubumba okugoqayo/okuqhumayo: Izithambisi ze-calcium zinc ezihlanganisiwe zidinga ukuhlanganiswa nezinto zokugcoba ezishisa kakhulu njenge-polyethylene wax ukuvimbela ukuncibilika ngokweqile;
Ukulungiswa kwamapharamitha enqubo: Ukucubungula izinga lokushisa eliphezulu (ngaphezu kuka-200 ℃) kudinga ukusetshenziswa kweziqinisi ezingamelani nokushisa (njenge-organotin, njll.) ukunciphisa i-torque ephezulu yokuncibilika ngaphezu kuka-15%. Imikhiqizo ecacile idinga ukulawula ukuhambisana phakathi kweziqinisi nama-resin ukuze kugwenywe imvula kanye nokwanda komswakama ngo-37.
4, Izindlela zokuqinisekisa nokuhlola
Ukuhlolwa kokuqina kokushisa: Beka isampula ye-PVC equkethe i-stabilizer ku-80 ℃ amahora angu-48 bese ubona ukushintsha kombala.
Ukulingisa ukumelana nesimo sezulu: Hlola umphumela wokuvikela i-UV ngokuhlolwa kokuguga kwe-QUV, okudinga izinga lokugcina amandla okudonseka elingu->85% ngemva kwamahora angu-5000.
Ukucubungula ukuqinisekiswa kokusebenza: Sebenzisa i-torque rheometer ukuqapha ukugeleza kokuncibilika nokwandisa isilinganiso sesithambisi kanye nesiqinisi.
Isikhathi sokuthunyelwe: Meyi-26-2025
