Nā pono a me nā pōʻino o ka hoʻohana ʻana i ka methyltin stabilizer no nā paipu PVC

Mea hoʻopaʻa wela tin organik (thiol methyl tin) 181 (no ke ao holoʻokoʻa)

Hana ʻo Bangtai Group i ka tin organik, kahi i ʻike mau ʻia e ka mākeke no kona kūlana paʻa a me ka hana maikaʻi loa, a hoʻoponopono pono i nā pilikia a nā mea hoʻohana e ʻike pinepine ai i kā lākou huahana: 1. kūlana paʻa ʻole; 2. ʻIke maikaʻi ʻole o ka huahana; 3. ʻAʻole kūpono ka maikaʻi o ka hoʻāʻo ʻana o ka huahana a ʻoi aku ka haumia ma mua o ke kūlana; 4. ʻO ka pilikia o ka ua ʻana o ka ʻili a me ka hoʻohana ʻana i nā mea hoʻohui haʻahaʻa ma ka huahana he kūpono loa ia no nā huahana hana PVC kiʻekiʻe me nā koi hana kiʻekiʻe, ke ʻike kiʻekiʻe, ke kūlana kiʻekiʻe, a me ka hana lima kiʻekiʻe.

Hoʻohana a me ka hana: He mea hoʻopaʻa wela thiol methyl tin kūpono, pili i ke kaiapuni, ʻaʻohe ʻawahia, a no ke ao holoʻokoʻa ʻo 181. Hoʻohana nui ʻia ia i nā pellets PVC, nā kiʻiʻoniʻoni PVC (me nā kiʻiʻoniʻoni hoʻemi wela, nā kiʻiʻoniʻoni paʻi), nā pepa PVC (me nā pepa paʻakikī, nā pepa semi hard, nā pepa blister) a me nā lāʻau lapaʻau ʻē aʻe, a me nā paipu moakaka like ʻole e like me nā paipu uea kila PVC a me nā paipu i hoʻoikaika ʻia me ke kaula pipi.

Hōʻike ka huahana i ke kala moakaka, ke ʻala māmā, ka haʻalulu haʻahaʻa, ka maikaʻi lōʻihi a paʻa, a me ke kūpaʻa mua a ma hope maikaʻi loa. Ma hope o ka hoʻohana ʻana, he nui nā ʻano o ka huahana e like me ke akahele kiʻekiʻe, ke kūpaʻa wela maikaʻi, ka nui o ka hoʻohui liʻiliʻi, ka hopena koʻikoʻi, a me ke ʻano paʻa.

ʻO ka Thiol methyl tin kahi mea hoʻopaʻa wela hana kiʻekiʻe no ka polyvinyl chloride (PVC)

Wahi a nā ʻoihana mana o ka honua, he kiʻekiʻe loa ke kūpaʻa wela o ka methyl tin, nā waiwai kala mua maikaʻi loa, a me ka mālamalama maikaʻi i nā mea hoʻopaʻa wela tin organik.

Ma lalo o ka hopena like, ʻoi aku ka liʻiliʻi o ka nui o ka methyl tin i hoʻohana ʻia ma mua o ka butyl tin a me ka octyltin.

Ua ʻāpono ʻia ʻo Methyltin e ka US FDA (21 CFR 178). I ka makahiki 2010, ua hōʻoia ʻia kēia huahana e ka German BGA (IIA, 4C) a hiki ke hoʻohana ʻia ma ke ʻano he mau mea hoʻopili meaʻai a me nā paipu wai, me ka palekana hilinaʻi.

ʻO nā huahana PVC e hoʻohana ana i nā mea hoʻopaʻa wela methyl tin he transparency maikaʻi a me ke kala maʻemaʻe.

Loaʻa iā ia ka hana hana kūpono a kūpono hoʻi no nā kaʻina hana like ʻole o ka polyvinyl chloride paʻa (PVC), e like me ka ʻōwili, extrusion, injection molding, a me ka blow molding.

Eia nō naʻe, i ka hoʻohālikelike ʻia me nā mea hoʻopaʻa ʻē aʻe, ʻoi aku ke kumukūʻai o ka thiol methyl tin, akā ʻoi aku ka haʻahaʻa o ka nui i hoʻohui ʻia.

Ka laulā pili:

ʻO ke kiʻiʻoniʻoni PVC (ʻoniʻoni hoʻopili wela, ʻoniʻoni paʻi, ʻoniʻoni ʻōwili, ʻoniʻoni wili, a pēlā aku)

Nā pepa PVC (nā pepa paʻakikī moakaka, nā pepa Kalikimaka, nā pepa hoʻolaha, nā pepa i hui pū ʻia, a pēlā aku)

Nā ʻāpana PVC (nā mea granular, nā pūpū lako kamaʻilio uila, a me nā mea ʻē aʻe)

Nā mea hana hale PVC (i loko o nā paipu like ʻole e like me nā paipu wai a me nā mea hoʻohui, nā paipu kemika, nā paipu ʻiʻo pipi, nā paipu ʻili nahesa, a pēlā aku)

Nā mea hoʻopili meaʻai PVC a me nā lako hale o kēlā me kēia lā

ʻO nā lako lapaʻau PVC (nā set infusion, a pēlā aku) a me nā huahana ʻē aʻe Ua hoʻokumu ʻia ʻo Bontecn Group Kina i ka makahiki 2003 e Longyang Chemical. Ke hana nei nā ʻoihana āpau o ka hui i ka hana ʻana i nā mea hoʻohui PVC a me nā mea hoʻohui rubber a me plastic. He hui ʻoihana ia e hoʻohui ana i ka noiʻi ʻepekema, ka hoʻomohala ʻana, ke kūʻai aku ʻana, ka lawelawe a me ka ʻoihana hoʻopukapuka kālā. Hana nui kā mākou hui i nā mea hoʻopaʻa me ka kaohi maikaʻi o ka huahana. No nā makahiki he nui, ua hana pū mākou me nā ʻoihana hui kaulana o ka honua, a ua hoʻokuʻu ʻia aku kā mākou huahana i ʻAmelika ʻĀkau, ʻAmelika Latina, ʻAsia Pākīpika, ka ʻAhahui ʻEulopa a me nā wahi ʻē aʻe, e loaʻa ana kahi kaulana i waena o kā mākou mea kūʻai aku.
