He nui nā mea hoʻohana ʻia ʻo Rigid PVC micro foamed material, e like me nā papa puaʻa (e like me nā papa wāwae foamed, nā ʻāpana pā pōhaku, nā pā a me nā pā kaupaku, nā tile kala hale, a me nā mea ʻē aʻe). ʻO nā alanui a me nā ala kaʻa, ke kūkulu ʻana i nā paipu hoʻoheheʻe, nā paipu wai ʻai mahiʻai, nā paipu pale ʻoihana, a me nā mea ʻē aʻe), nā ʻaoʻao i hoʻoheheʻe ʻia (e like me nā pale pale, nā ʻaoʻao o ka puka pani, nā ʻaoʻao puka a me nā pukaaniani Balcony panel profile, loko a me waho o ka papahele, etc.) .

① ʻO ka hoʻohua manuahi e pili ana i ka hoʻonui manuahi ʻole ʻia o ka heheʻe i ka wā e haʻalele ai i ka make, a laila komo i ka mea hoʻonohonoho me ka nui nui ma hope o kahi manawa pōkole. Hoʻokumu ka huʻa manuahi i nā ʻōhū a pau ma ka ʻāpana keʻa o ka extrudate.

② ʻO ke ʻano hoʻohāhā i loko, ke ʻano ʻili ʻili a i ʻole ke ʻano celuka e hoʻohana i kahi make kūikawā me ke kumu o loko e hoʻokaʻawale i nā mea i hoʻopaʻa ʻia, pili ka mea hoʻonohonoho me ka die, a ua like kona ʻano o waho me ko ka make. Ke hoʻouna ʻia ka mea i ka lima hoʻonohonoho i mua o ka make inlet, e komo ka mea hoʻoheheʻe i loko o ka mea hoʻohāhā i loko o ka lima hoʻonohonoho hoʻomaha i ka wā e haʻalele ai i ka kiʻiʻoniʻoni waha, a hoʻomaʻamaʻa wikiwiki i ka ʻili holoʻokoʻa, i mea e pale ai i ka hoʻokumu ʻana. o ka ohu a me kekahi pehu ma ka pauku o ka extrudate, i mea e hana ai i papa ili ma ka ili. I ka manawa like, ʻo ke kumu i loko o ka make e hana i ka lua i hana ʻia i loko o ka huahana semi-finished i hoʻopiha ʻia me ka huʻa i hana ʻia e ke koena hehee, ʻo ia hoʻi, ka huʻa i loko. Ma ka hoʻomalu ʻana i ka ikaika hoʻoluʻu, hiki ke loaʻa nā huahana me ka mānoanoa o ka ʻili o 0.1 ~ 10mm a me ka mānoanoa pā o nā huahana ma mua o 6mm. Hiki i kēia ʻano hana ke hana i nā profiles me ke ʻano ʻāpana keʻa paʻakikī. Loaʻa i nā huahana nā hiʻohiʻona o ka ʻili maʻemaʻe, ka paʻakikī kiʻekiʻe a me ka haʻahaʻa haʻahaʻa ma ka wahi kumu. Eia kekahi, ma ka hoʻohui ʻana i kēia ʻano me ke ʻano ①, hiki ke loaʻa kahi huahana me ka ʻili ma kekahi ʻaoʻao a me ka mokuʻāina manuahi ma kekahi ʻaoʻao.

③ Hoʻohana ʻo Coextrusion i ke poʻo i hui pū ʻia a me ʻelua extruders e hoʻokuʻu i ka ʻili o ka ʻili ʻole a me ka ʻūhā kumu. Hiki ke hoʻololi ʻia ke ʻano a i ʻole ka ʻano o nā ʻāpana ʻelua o nā plastics e like me nā pono e hoʻokō ai nā huahana i ka nui a me ka nui i koi ʻia e ka maʻamau. ʻO ka hapa nui o nā paipu puaʻa kumu i hana ʻia ma Kina e hana ʻia e kēia kaʻina hana.
