ʻO ka Plasticization e pili ana i ke kaʻina o ka ʻōwili ʻana a i ʻole ka hoʻokuʻu ʻana i ka ʻōpala maka e hoʻomaikaʻi i kona ductility, flowability, a me nā waiwai ʻē aʻe, i mea e maʻalahi ai ka hana ʻana e like me ka molding.
1. Nā kūlana hana:
Ma lalo o nā kūlana kaʻina hana maʻamau, piʻi ka nui o ka plasticization o ka resin PVC me ka piʻi ʻana o ka mahana hana a me ka helu shear. ʻOi aku ka kiʻekiʻe o ka mahana hana, ʻoi aku ka nui o ka ʻokoʻa wela, a ʻoi aku ka wikiwiki o ka hoʻoili wela. Ma muli o ka PVC he mea hoʻokele maikaʻi ʻole o ka wela, ʻo ka piʻi ʻana o ka wikiwiki shear e hoʻolalelale i ka hana wela frictional ma waena o nā mea, a me ke alapine o ka hoʻopili ʻana ma waena o nā mea a me nā mea hana, e hoʻomaikaʻi ai i ka hoʻololi ʻana i ka wela.
2. ʻO ka hana resin:
Hoʻonui ka mahana hoʻololi aniani a me ka helu heheʻe o PVC me ka piʻi ʻana o ka paona molekala a me ka crystallinity, a paʻakikī hoʻi ka pae plasticization o PVC.
3: Nā kumu kumu
ʻO ka hoʻohanaʻana i nā lubricants, plasticizers, nā mea kōkua, nā mea hoʻololi i ka hopena, nā mea hoʻopihapiha, nā stabilizers, a me nā mea'ē aʻe i loko o ke kaʻina hana PVC he hopena nui i nā waiwai o ka PVC plasticization. ʻOiaʻiʻo, ʻokoʻa nā ʻāpana like ʻole a me nā pae o ka hopena i nā waiwai plasticization o PVC ma muli o kā lākou noi noi ʻokoʻa.
4. ʻO ka hui ʻana a me ke kaʻina hana
ʻO ka hui ʻana ke kaʻina o ka homogenizing PVC resin me nā mea hoʻohui e like me nā stabilizers wela, modifiers, lubricants, fillers, a me nā puaʻa. ʻO nā mea hana nui i hoʻohanaʻia he mīkini kukini kiʻekiʻe a me ka mea hui hoʻoluʻu. ʻO ke kaʻina hana hui e hilinaʻi ʻia i ka friction a me nā ikaika shear i hana ʻia e nā mana mechanical ma luna o ka mea e hoʻomaʻemaʻe a wela i ka mea, hoʻoheheʻe i kekahi mau mea hoʻohui a uhi iā lākou ma ka ʻili o ka resin PVC. Hoʻomaʻemaʻe ʻia ka resin PVC ma lalo o ka ʻoki a me ka friction, a ʻike ʻia kona ʻili a palupalu a porous ma lalo o ka mahana. Hoʻopili ʻia ka mea kōkua ma ka ʻili a hiki i ka homogenization. Piʻi hou ka mahana, a heheʻe ka ʻili o nā ʻāpana, e hopena i ka piʻi ʻana o ka nui o ka nui
