ʻO nā lubricants nā mea hoʻohui pono i ka hana PVC.No nā lubricants, hiki ke hōʻuluʻulu ʻia nā hana maʻamau i ka ʻoihana i ʻelua mau kiko.ʻO lākou: hiki iā ia ke hoʻemi i ka friction like ma waena o nā ʻāpana a me nā macromolecules ma PVC heheʻe ma mua o ka hoʻoheheʻe ʻana;E ho'ēmi i ka friction like ma waena o PVC melt a me ka plastic mechanical contact surface.Ma ka ʻatikala o kēia lā, ʻo ka mea hana o Sainuopolyethylene waxe lawe iā ʻoe e nānā i ka lubrication kūloko a me waho o nā lubricants PVC mai kahi ʻike loea!

1. Lubrication kūloko
ʻO ka lubrication kūloko o nā lubricants, ma ke ʻano o PVC, hiki ke noʻonoʻo ʻia i ke ʻano o ka mea like me ka plasticizers, e pāʻani ana i kahi hana plasticizing a palupalu paha.ʻO ka ʻokoʻa, ʻo ka lubricants ka polarity haʻahaʻa a me nā kaulahao kalapona lōʻihi, e hōʻemi nui i ka hoʻohālikelike ʻana ma waena o nā lubricants a me ka polyvinyl chloride i hoʻohālikelike ʻia me nā plasticizers.Ma muli o ka haʻahaʻa haʻahaʻa (a me kekahi mau hoʻohālikelike) ma waena o nā lubricants a me ka polyvinyl chloride, hiki i kahi liʻiliʻi o nā molekala lubricant ke komo i waena o nā kaulahao polymer molecular e like me plasticizers, hoʻonāwaliwali i ka huki like ʻana ma waena o nā kaulahao mole, a me ka hoʻololi ʻana o ka polymer, nā kaulahao Molecular. ʻoi aku ka maʻalahi o ka hoʻoheheʻe ʻana a me ka hoʻololi ʻana me kekahi, ʻoiai ʻaʻole e hoʻemi nui i ka mahana hoʻololi aniani o ka polymer.
2. Lubrication waho
ʻO ka lubrication waho e pili ana i ka mīkini lubrication interface.Nā Lubricantspili i ka ʻili o ka resin hoʻoheheʻe ʻia a i ʻole ka ʻili o ka mīkini hoʻoponopono a me nā mole e hana i kahi papa mole lubricant.Ma muli o ka loaʻa ʻana o nā papa mole lubricant, ua hoʻokumu ʻia kahi interface lubrication, e hōʻemi ana i ka friction ma waena o ka resin a me ka mīkini hana.ʻO ka viscosity o ka lubrication interface film a me kona pono lubrication e pili ana i ka helu hoʻoheheʻe a me ka mahana hana o ka lubricant.ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o ka lubrication o nā lubricants me nā kaulahao kalapona molekala lōʻihi ma muli o ko lākou hiki ke mālama i ʻelua mau wahi friction.

3. He aha ka hana inā ʻaʻole hoʻohana maikaʻi ʻia ka lubricant PVC?
ʻO ka huaʻōlelo 'mea liʻiliʻi, hopena maikaʻi' e wehewehe i nā lubricants PVC.ʻO ka hana o nā lubricants PVC i ka hana PVC ʻaʻole i emi iki ma mua o nā stabilizers.ʻO kona hoʻohana maʻamau e hahai i nā loina koʻikoʻi, e like me ke koena hoʻoheheʻe kūloko a me waho, dosage moderate, a me nā mea ʻē aʻe. ʻaʻole hoʻohana maikaʻi ʻia?
(1) Lubrication i loko a me waho i kaulike ʻole
ʻO ka nui o ka hoʻoheheʻe ʻana i waho, ʻoiai ʻo ka wikiwiki o ka extrusion wikiwiki, ʻoi aku ka maikaʻi o ka mea i ka ulu a maikaʻi ʻole ka plasticization;ʻOi aku ka nui o ka hoʻoheheʻe ʻana i loko, ka nui extrusion nui, a me ka plasticization waiwai maikaʻi ʻole.Hiki i ka lubrication mua maika'i ke ho'oulu i ka torque extrusion.ʻAʻole lawa ka lubrication i ka pae hope hiki ke alakaʻi i ka lawa ʻole o ka lubrication i ka ʻāpana homogenization, ka pauku hoʻoemi, a me ka pauku make o ka wili, e hopena i ka ʻoki ʻana i nā mea nui a pili i ka maikaʻi o ka ʻili a me ka hana kūloko o ka huahana extruded.I nā hihia koʻikoʻi, hiki ke hana i ka decomposition.

(2) Ka nui o ka lubricant i hoʻohana ʻia
ʻAʻole ʻoi aku ka maikaʻi o nā lubricants me nā nui nui.Ma muli o ka like ʻole ma waena o nā lubricants a me ka resin PVC, hiki i ka hoʻohui nui ʻana o nā lubricants ke loaʻa nā hopena ʻino i ka ʻōnaehana hui PVC.ʻO ke koena o loko a me waho o ka lubrication i ʻōlelo ʻia aia i loko o kahi palena, no ka mea, he hopena ʻino ka lubricant a me ka polyvinyl chloride blend system.I ka hana maoli, nui nā pilikia hoʻoponopono a me nā pilikia e pili ana i ke kūpaʻa wela, a me nā hemahema he nui i nā huahana, hiki ke kumu i ka hoʻohana nui ʻana i ka lubricant.
No nā kikoʻī hou aku, e ʻoluʻolu e nīnau mai iā mākou!ninau
Hui Qingdao Sainuo.ʻO mākou ka mea hana no ka PE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc / Calcium Stearate….Ua hala kā mākou huahana i ka REACH, ROHS, PAHS, FDA hoʻāʻo.
ʻO Sainuo, e hoʻokipa i kāu nīnau!
