Ke hoʻohālikelike ʻia me nā huahana extruded plastic ʻē aʻe, ʻo ka SUZHOU SUPXTECH hana ʻana i nā huahana plastik PVC haʻahaʻa ʻili haʻahaʻa ʻaʻole pono ka plasticization maikaʻi ma lalo o kekahi kaomi hoʻoheheʻe ʻana, akā loaʻa pū kekahi i nā koi ʻenehana kūpono no ka nui, ka nui a me ke kūlike o nā lua pua, a me ka mānoanoa, paʻakikī, ʻōlinolino a me ka pau ʻana o ka ʻili.ʻAʻole pili wale ka maikaʻi o ke kino huʻihuʻi i ke ʻano a me nā mea maka, akā pili pono a hoʻopaʻa ʻia e ka hana shear o extruder screw, hoʻoheheʻe kaomi, wela, extrusion (traction) wikiwiki, mold lip gap, mold mold gap, cooling. ka wela o ka wai a me nā mea ʻē aʻe.No laila, ke hoʻohālikelike ʻia me nā huahana plastik extruded ʻē aʻe, loaʻa i nā huahana plastic foam ʻili kahi pilikia ʻenehana, mai ka hoʻomaʻamaʻa a me ke kumumanaʻo he nui nā pilikia i hoʻoholo ʻole ʻia e pono i nā ʻenehana ʻoihana e aʻo a hoʻoponopono.

1, ka ʻili ʻili ʻili PVC pepa ʻenehana hana ʻenehana a me nā hiʻohiʻona

ʻO ka paʻakikī o ka ʻenehana i ka hana ʻana i nā huahana plastik PVC e hoʻohāhā ka ʻili.ʻO ka foaming ka hopena o ka hoʻonui a me ka hoʻonui ʻana o ka melt viscosity, ke kaomi kinoea i hana ʻia e ka mea hoʻoulu a me ke kaomi o ka lewa.

ʻO ke kaʻina hana hoʻohua maʻamau e hele i ʻekolu mau pae:

(1) Hoʻoheheʻe ʻia ke kinoea e hoʻoheheʻe ʻia i loko o ka hui ʻaʻahu plasticized e hoʻoheheʻe ʻia ma kahi mahana a me ke kaomi i loko o ka extruder a hiki i ke kūlana saturation e hana i ka ʻōpū ʻōpū;

(2) Hoʻokuʻu ʻia ka heheʻe mai ka make, a me ka hoʻokuʻu ʻana i ke kaomi, ʻo ka supersaturated dissolved gas nucleates, hoʻonui a precipitates, e hana ana i nā puka ʻaʻahu a me nā puʻupuʻu ʻeleʻele i ka āpau o ka formwork;

(3) Ma lalo o ka hopena ʻoluʻolu o ka mea hoʻoheheʻe ʻia, hoʻopaʻa ʻia a hoʻohālikelike ʻia nā huahana huʻi.Loaʻa nā hiʻohiʻona o ka nui a me ka ʻeleʻele ʻeleʻele o ka ʻili ʻili maikaʻi loa i nā huahana plastik PVC, ka liʻiliʻi a me ka ʻaʻahu, ka nui a me ka mānoanoa e hoʻokō i nā koi, nā hiʻohiʻona maikaʻi, ka paʻakikī kiʻekiʻe a me ka ʻōlinolino.

2, ili huʻihuʻi PVC papa palaka kumu maikaʻi

ʻO nā kumu waiwai nui e pili pono ana i ka maikaʻi o ka hoʻolālā ʻana o ka ʻōpala plastik ʻo ia ka foaming agent a me ka foaming harmonizer.ʻO nā mea maka e like me ka stabilizer, lubricant, calcium carbonate a me ke kaʻina hana extrusion hiki ke hoʻoikaika a hoʻonohonoho i ka maikaʻi o ka foaming i kekahi ʻano.No ka mea, ʻo ka mahana o ka plasticization o ka heheʻe i ke kaʻina extrusion o nā huahana foaming pono e emi iki ma mua o ka decomposition wela o ka foaming agent, ʻo ka haʻahaʻa haʻahaʻa o ka polymerization o ka resin PVC, ʻo ka haʻahaʻa haʻahaʻa o ka mahana hana e pono ai no ka hoʻoheheʻe plasticization.No ka loaʻa ʻana o nā huahana plastik i hoʻopiha piha ʻia, ʻaʻole pono ke kiʻekiʻe o ka viscosity resin.I ka manawa like, ke hoʻohālikelike ʻia me nā huahana huʻihaʻi ʻē aʻe, no ka mea ʻoi aku ka laulā o ka ʻāpana keʻa o ka pepa, mai ke poʻo extrusion i loko o ka waha make e puʻunaue ʻia i kahi ākea o kahi 1.3m, i mea e maʻalahi ai ka hoʻopuehu ʻana a me ka hoʻonui ʻana o nā ʻōpū. , Pono e hoʻohui ʻia ke kaomi o ka pauku keʻa holoʻokoʻa o ka pepa, ʻoi aku ka nui o ka wai o ka heheʻe, a ʻoi aku ka liʻiliʻi o ke kaumaha o ka resin.E like me ka SC-7 a i ʻole SC-8 ka hoʻokuʻu ʻana i ka resin loose ʻoi aku ka maikaʻi.SUZHOU SUpxTECH
