ʻO ka heat stabilizer kekahi o nā mea hoʻohui nui i ka hana PVC.Hoʻohana ʻia ʻo PVC heat stabilizer i kahi helu liʻiliʻi, akā nui kāna kuleana.ʻO ka hoʻohana ʻana i ka stabilizer wela i ka hana PVC hiki ke hōʻoia ʻaʻole maʻalahi ka PVC a paʻa.ʻO kapolyethylene waxhoʻohana ʻia i ka PVC stabilizer e hoʻokō i ka hopena kaulike lubrication.I ke kaʻina hana o ka huahana, kūpono ia i ka plasticization, dispersion a me ka hui ʻana, ka hana ʻana i nā hiʻohiʻona a me ke kahe kahe kaulike;A e hoʻokō i ka conduction wela a me ke kaulike me ka ʻole adhesion a me ka paʻa;ʻO ka mea maʻamau, e noʻonoʻo i ke kaʻina o ka PE wax (lubricant) a me nā pae mua, waena a me ka hope.I ka manawa like, e noʻonoʻo ʻia ka maʻalahi o ka stabilizer, e noʻonoʻo ana i ka maʻalahi o loko a me waho.

ʻO nā mea hoʻopaʻa wela i hoʻohana mau ʻia i ka hoʻoili ʻana o PVC me nā mea hoʻopaʻa paʻakai alakaʻi kumu, nā mea hoʻopaʻa kopa metala, nā mea hoʻopaʻa organotin, nā mea hoʻopaʻa honua ʻokoʻa, nā pūhui epoxy, etc.
Mea hoʻopaʻa paʻakai alakaʻi
ʻO ka paʻakai alakaʻi ka mea hoʻopaʻa wela maʻamau no PVC, a hiki i kāna helu ke helu no ka hapalua o ka PVC heat stabilizer.
ʻO nā mea maikaʻi o ka paʻakai paʻakai paʻakai: maikaʻi ke kūpaʻa wela, ka lōʻihi o ka wela wela, ka hoʻokaʻawale uila maikaʻi loa a me ke kūpaʻa maikaʻi.
ʻO nā hemahema o ke alakaʻi paʻakai stabilizer: maikaʻi ʻole ka hoʻopuehu ʻana, kiʻekiʻe ka ʻawaʻawa, kala mua, paʻakikī ke loaʻa nā huahana alohilohi a me nā huahana kala ʻulaʻula, nele o ka lubricity, i mea e hana ai i ka sulfur a hoʻokaʻawale i ka pollution.
ʻO nā mea hoʻopaʻa paʻakai alakaʻi maʻamau:
Tribasic lead sulfate, molecular formula: 3PbO · PbSO4 · H2O, code TLS, pauda keʻokeʻo, density 6.4g/cm3.ʻO Tribasic lead sulfate kahi mea hoʻopaʻa maʻamau.Hoʻohana maʻamau ia me ka dibasic lead phosphite.Pono e hoʻohui ʻia ka lubricant no ka mea ʻaʻohe ona lubricity.Hoʻohana nui ʻia ia i nā huahana opaque paʻakikī PVC, a ʻo ke ʻano he 2 ~ 7 mau ʻāpana.
Dibasic lead phosphite, molecular formula: 2PbO · pbhpo3 · 1 / 2H2O, code DL, pauda keʻokeʻo, density 6.1g/cm3.ʻOi aku ka liʻiliʻi o ke kūpaʻa wela o ka phosphite lead dibasic ma mua o ka tribasic lead sulfate, akā ʻoi aku ka maikaʻi o ka pale ʻana i ka wā ma mua o ka tribasic lead sulfate.Hoʻohana pinepine ʻia ka dibasic lead phosphite me ka tribasic lead sulfate, a ʻo ke ʻano maʻamau ma kahi o ka hapalua o ka tribasic lead sulfate.
ʻO Dibasic lead stearate, code i kapa ʻia ʻo DLS, ʻaʻole like me ka tribasic lead sulfate a me ka dibasic lead phosphite a he lubricity.Hoʻohana pinepine ʻia me ka tribasic lead sulfate a me ka dibasic lead phosphite i ka nui o 0.5 ~ 1.5 phr.
I mea e pale aku ai i ka lele ʻana o ka pauka paʻakai paʻakai paʻakai, hoʻohaumia nui i ke kaiapuni hana a hoʻomaikaʻi i ka hopena dispersion o ka stabilizer, ua hoʻomohala ʻia a hoʻohana ʻia ka mea hoʻokele paʻakai paʻakai lepo lepo ʻole ma ka home a ma waho.ʻO ke kaʻina hana:
Ma lalo o ka hoʻomehana ʻana a me ka hui ʻana, hoʻopuehu piha ʻia nā ʻano paʻakai paʻakai like ʻole a me nā mea hoʻokele wela kōkua me nā hopena synergistic a hui pū ʻia me nā lubricants o loko a me waho e hana i nā mea hoʻopaʻa paʻakai paʻakai paʻakai.Hiki iā ia ke hoʻokō i nā koi loea o ka thermal stability a me ka lubrication kūloko a me waho ma o ka hoʻohui ʻana iā ia i ka resin PVC e like me kekahi helu o nā ʻāpana (me ka ʻole o ka hoʻohui ʻana i nā stabilizers a me nā lubricants).
Ua hōʻike ʻia ʻo ke alakaʻi paʻakai stabilizer i hoʻohana ʻia i ka hana ʻana i ka lepo-noa ka paʻakai composite stabilizer he mau ʻāpana maikaʻi, e hoʻonui ai i ka ʻili o ka hopena me ka hydrogen chloride.No ka mea ua hui pū ʻia me nā lubricants o loko a me waho, ua hoʻopuehu maikaʻi ʻia, hoʻomaikaʻi maikaʻi ʻia ka maikaʻi o ka thermal stability a me ka hōʻemi ʻana.

Kopa metala
ʻO ka nui o ka stabilizer nui ka lua o ka nui ma hope o ka paʻakai paʻakai.ʻOiai ʻaʻole maikaʻi kona kūpaʻa wela e like me ka paʻakai kēpau, he lubricity pū kekahi.ʻAʻohe mea ʻawaʻawa koe wale nō ka CD a me ka Pb, ʻaʻole ʻo Pb a me Ca, a ʻaʻohe haumia vulcanization.No laila, hoʻohana nui ʻia ia i ka PVC palupalu, e like me ka non-toxic a me ka maopopo.
Hiki i nā kopa metala ke metala (lead, barium, cadmium, zinc, calcium, etc.) nā paʻakai o nā ʻakika momona (lauric acid, stearic acid, naphthenic acid, etc.), ma waena o ia ka stearate ka mea maʻamau.ʻO ke kauoha o ka paʻa wela: ka paʻakai zinc> paʻakai cadmium> paʻakai alakaʻi> paʻakai calcium / paʻakai barium.
ʻAʻole hoʻohana wale ʻia nā kopa metala.Hoʻohana pinepine ʻia lākou ma waena o nā kopa metala a i hui pū ʻia me nā paʻakai kepau a me ka tin organic.
ʻO Zinc stearate (znst), ʻaʻohe mea ʻawaʻawa a ʻaʻole hoʻi, he maʻalahi ke hana i ka "zinc kuni", i hoʻohana pinepine ʻia me nā kopa BA a me Ca.
Hoʻohana pinepine ʻia ka calcium stearate (CAST), me ke kaʻina hana maikaʻi, ʻaʻohe haumia sulfide a me ka ʻike, hoʻohana pū ʻia me ka kopa Zn.
ʻO ka Cadmium stearate (cdst), ma ke ʻano he mea hoʻokūpaʻa koʻikoʻi koʻikoʻi, he mea ʻawaʻawa nui a ʻaʻole kū i ka pollu sulfide.Hoʻohana pinepine ʻia me ka kopa BA.
Lead stearate (PBST), me ke kūpaʻa wela maikaʻi, hiki ke hoʻohana ʻia e like me ka lubricant.He maʻalahi ka hoʻoheheʻe ʻana o nā mea pōʻino, ʻikeʻole ʻia, ʻawaʻawa a me ka haumia sulfide koʻikoʻi.Hoʻohana pinepine ʻia me nā kopa BA a me CD.
Barium stearate (BST), non-toxic, anti sulfide pollution, akaka, hoʻohana pinepine ʻia me nā kopa Pb a me Ca.
Hōʻike nā hopena noiʻi a me ka hoʻomaʻamaʻa ʻana ʻaʻole kūpono ke hoʻohana wale ʻia ka mea hoʻopaʻa wela kopa metala, a hiki ke loaʻa ka hopena synergistic maikaʻi ma ka hoʻohana pū ʻana.Ma muli o ka ʻokoʻa o ka ʻāpana anionic, synergist, solvent a i ʻole ka hoʻopuehu ʻana o ke kopa metala heat stabilizer, hiki ke hoʻokaʻawale ʻia ka mea hoʻoheheʻe metala metala wela i ka paʻa a me ka wai.
ʻO ka calcium stearate a me ka zinc he mau mea hoʻomaha wela non-toxic me ke kumu kūʻai haʻahaʻa, kūpono i nā huahana PVC no ka hoʻopili meaʻai.Hōʻike nā hualoaʻa he kiʻekiʻe ka ikehu ionization o ka zinc soap stabilizer, hoʻopili me ka allyl chloride ma ka mole PVC, hiki ke hoʻopaʻa i ka PVC a keʻakeʻa i ka hopena kala mua.Eia nō naʻe, ʻo ZnCl2 i hana ʻia e ka hopena he mea hoʻoikaika no ka wehe ʻana i ka HCl a hiki ke hoʻoikaika i ka hoʻohaʻahaʻa ʻana o PVC.ʻAʻole hiki i ke kopa calcium i hui ʻia ke hana me HCl wale nō, akā, e hana pū me ZnCl2 e hana i ka CaCl2 a hoʻohou i ka kopa zinc.ʻAʻohe hopena catalytic o CaCl2 i ka wehe ʻana o HCl, a ʻo ka paʻakikī o ZnCl2 me nā derivatives calcium hiki ke hōʻemi i kona hiki ke hoʻopau i ka HCl.ʻO ka hui pū ʻana o nā pūhui epoxy me nā kopa calcium a me ka zinc he hopena synergistic maikaʻi.ʻO ka maʻamau, ʻo ka non-toxic composite heat stabilizer ka mea nui o ka calcium stearate, zinc stearate a me ka epoxy soybean oleate.He mea pono e hoʻomaopopo i kēlā, β- ʻO ka hui pū ʻana o diketone hou auxiliary heat stabilizer a me ka calcium a me ka zinc soap stabilizer e hoʻonui i ka hoʻohana ʻana i ka calcium non-toxic a me ka zinc composite stabilizer.Hoʻohana ʻia ia i kekahi mau mea hoʻopili meaʻai e like me nā hue PVC a me nā ʻāpana.
