Kaʻina hana hose PVC:

Ka hui ʻana → kneading → extrusion granulation → extrusion forming → traction → coiling → packaging → nānā maikaʻi → huahana pau

1. Kawili ʻana i nā mea ʻai

ʻO nā ʻano mea maka a pau ke kaupaona pololei ʻia a hoʻokomo ʻia i loko o ka kneader ma kahi ʻano.Kaʻina hānai: PVC resin, plasticizer, stabilizer, lubricant.Ke piʻi ka mahana i 100 ~ 110 ℃, hiki ke hoʻokuʻu ʻia ka mea.

2.extrusion granulation

ʻO kēia kaʻina hana no ka mālama ʻana i ka mahana, ʻo ke kiʻekiʻe kiʻekiʻe o ka wela o ka mea pono e hoʻomalu ʻia ma kahi kiʻekiʻe ma mua o ka wela hoʻoheheʻe o ka mea, haʻahaʻa ma mua o ka extrusion molding temperature, ʻo ia hoʻi, ma waena o 155 ~ 160 ℃.Pono ka Granulation e hoʻokō i ke kumu o ka hui ʻana a me ka plasticization mua.

ʻO ka mahana o kēlā me kēia wahi o ka granulator penei:

Wahi o 80 ~ 90 ℃;Wahi o 130 ~ 140 ℃;ʻEkolu wahi 140 ~ 150 ℃;E hoʻomaka ana mai 150 ~ 160 ℃.

3. extrusion paipu hana

ʻOi aku ka kiʻekiʻe o ka mahana o ka extrusion tube.Ma keʻano laulā, pili ka ʻike o ka paipu i ka mahana hana.I kekahi pae wela, maikaʻi ka transparency wela kiʻekiʻe, a me ka hope.I ka manawa like, e hoʻopili ka wikiwiki o ka traction a me ka wikiwiki i ka ʻike o ka paipu.ʻOi aku ka nui o ka traction, ʻoi aku ka wikiwiki o ka hoʻoilo, a ʻoi aku ka maikaʻi o ka ʻike o ka paipu.ʻO ka wikiwiki o ka traction ʻo 10% ~ 15% ʻoi aku ka wikiwiki ma mua o ka wikiwiki extrusion.Hoʻomoʻa ʻia ka hoʻoluʻu ʻana o ka hose alohilohi me ka wai anuanu ma ka make o ka ihu a laila hoʻomaloʻo i loko o ka pahu wai.

ʻO ka mahana o kēlā me kēia wahi o ka hoʻoheheʻe extrusion penei:

Wahi 1:90 ℃;Wahi ʻelua 140 degere 5 ℃;ʻEkolu mau ʻāpana 160 degere 5 ℃;ʻEhā ʻāpana 170 degere 5 ℃.

4. PVC hose extrusion e mālama ai:

1. pololei me ka pauda extrusion molding, ka wela o ka extruder ma kahi o 5 ℃ haʻahaʻa ma mua o ka mea granular.

2. Ma waho aʻe o ke anawaena liʻiliʻi (φ60mm ma lalo) ʻaʻole pono e puhi ʻia ka hoʻoheheʻe ʻana o ka paipu i loko o ka ea i hoʻopaʻa ʻia, pono e puhi ʻia ka nui o ke anawaena o ka puʻupuʻu blank i loko o ka ea i hoʻopaʻa ʻia, i mea e hōʻoia ai i ka pololei a me ka paʻa o ka nui anawaena paipu.E hoʻolohe i ke kaomi paʻa o ka ea paʻa.

3. E noʻonoʻo i ka paʻa o ka wikiwiki traction a pale i ka hoʻololi ʻana o ke anawaena paipu a i ʻole ka mānoanoa o ka paia i hoʻokumu ʻia e ka traction instability.

4. Inā paʻa ka mīkini no ka manawa lōʻihi, pono e wehe a hoʻomaʻemaʻe ʻia e pale i nā pilikia decomposition.
