Nā mea waiwai no ka hana ʻana i nā paipu PVC
Nā mea waiwai no ka hana ʻana i nā paipu PVC,
PVC Resin, PVC e hana i ka paipu,
Hoʻokumu ʻia ka resin polyvinyl chloride S-1000 ma ke kaʻina hana polymerization hoʻokuʻu me ka hoʻohana ʻana i ka monomer vinyl chloride ma ke ʻano he mea maka.He ʻano ia o ka polymer pūhui me ka pili pili o 1.35 ~ 1.40.ʻO kona helu hoʻoheheʻe ma kahi o 70 ~ 85 ℃.ʻO ke kūpaʻa wela maikaʻi ʻole a me ke kūpaʻa māmā, ʻoi aku ma mua o 100 ℃ a i ʻole ka manawa lōʻihi ma lalo o ka lā e hoʻomaka ana ka hydrogen chloride e decompose, pono e hoʻohui i nā stabilizers.Pono e mālama ʻia ka huahana i loko o kahi hale kūʻai maloʻo a ventilated.E like me ka nui o ka plasticizer, hiki ke hoʻololi i ka palupalu plastic, a hiki ke loaʻa i ka resin paste e ka emulsion polymerization.
Hiki ke hoʻohana ʻia ka papa S-1000 no ka hana ʻana i ke kiʻiʻoniʻoni palupalu, ka pepa, ka ʻili i hana ʻia e ke kanaka, ka paipu, ka pahu hoʻoheheʻe ʻia, ka lalo, ka paipu pale kaula, ka paʻi kiʻiʻoniʻoni, kaʻili a me nā mea palupalu ʻē aʻe.

Hana ʻia nā paipu PVC e ka extrusion o nā mea maka PVC, a maʻamau e hahai i nā ʻanuʻu like o nā hana extrusion paipu maʻamau:
1. ʻO ka hānai ʻana i ka pauka maka i kapa ʻia he resin a me ka hoʻopiha i loko o ka PVC twin screw extruder;
2. Hee a me ka wela ma na wahi extruder lehulehu;
3. Ka hoʻokuʻu ʻia ʻana ma o ka make e hana i loko o ka paipu;
4. ʻO ka hoʻoluʻu o ka paipu i hoʻohālikelike ʻia (ma ke kāpī ʻana i ka wai ma ka paipu);a
5. ʻO kaʻokiʻana i nā paipu PVC i ka lōʻihi i makemakeʻia.
ʻO nā mea maka no ka hana ʻana i nā paipu PVC he resin a me ka mea hoʻopiha (ʻoi aku ka nui o ka calcium carbonate, a i ʻole i ʻike ʻia he pōhaku).ʻO ka hui maʻamau ʻo 1 kilogram (kg) o ka resin me 1 kilogram o ka hoʻopiha.ʻO ka hapa nui o nā kaʻina hana, me nā limahana e hānai ana i nā mea maka i ka hoʻomaka ʻana o ke kaʻina hana, ka nānā ʻana i ka mahana o ke kaʻina hana a me ka nānā ʻana i ka huahana hope no nā hemahema ʻike ʻia ma mua o ka hoʻopaʻa ʻana a me ka hoʻouna ʻana i nā mea kūʻai.Ua aʻo ʻia nā limahana a pau a hiki iā lākou ke hana i kēia mau hana a pau me ka mākaukau.ʻO ka mea nui no ka hana ʻana i nā paipu PVC he mea pauka i kapa ʻia ʻo PVC resin.
