Ka loiloi ʻenehana no ka hoʻopaʻa ʻana i ke ahi a me ka hoʻokō ʻana i nā kemika me ke alakaʻi ʻole i ka PVC Co-extruded Foam Board Construction.

He mea hana nui ʻo Jiatao Industrial Co., Ltd. i nā ʻenehana plastik polyvinyl chloride ma Kina, kūikawā i ka hana nui ʻana o nā papa pahu kiʻekiʻe kiʻekiʻe a me nā composites plastic-wood. Ke hana nei ma ke ʻano he kumu hana ʻoihana me ka nui o ka makahiki ma mua o 25,000 tons, hoʻohana kā mākou hale i ka ʻenehana extrusion kiʻekiʻe a me nā kaʻina hana hoʻomaha hoʻomaha. Hoʻolālā ʻia kā mākou huahana no nā mākeke kiʻekiʻe e like me ʻAmelika Hui Pū ʻIa, Kelemānia, a me Iapana, e lawelawe ana i nā ʻāpana koʻikoʻi e like me ka hoʻonaninani hale, ka hana ʻana i nā lako, a me nā mea lawe kaʻa. Ma ke ʻano he mea hoʻolako hoʻolālā i nā ʻoihana Fortune 500, hōʻoia ʻo Jiatao i kēlā me kēia pvc co-extruded foam papa e hoʻokō i nā kauoha palekana a me nā kaiapuni i koi ʻia no ka hoʻohui ʻana i ka hale kūkulu hou, e kālele ana i ka paʻa polymer a me nā kemika hoʻohui ʻole.

ʻO ke ʻano o ke ahi a me ka UL 94 V-0 ka hoʻopaʻa ʻana i ke ahi

Ma nā papahana hoʻolālā o kēia wā, ka nā mea pale ahi o ka PVC foam board ua helu ʻia e ka UL 94 vertical burning test. No ka hoʻokō a UL 94 V-0 i helu ʻia i ka pvc co-extruded foam papa , pono e hōʻike ka mea i ka hana hoʻopau iā ia iho i loko o 10 kekona ma hope o ka wehe ʻia ʻana o ke ahi, me ka ʻole o nā kulu lapalapa. ʻO ka ka hopena synergistic o nā mea pale ahi ma PVC , e like me antimony trioxide a i ʻole alumina trihydrate, he mea koʻikoʻi no ka hoʻonui ʻana i ka Limiting Oxygen Index (LOI) i nā waiwai ma luna o 32 pakeneka. Ke kālailai No ke aha e pono ai ke ahi i helu ʻia ʻo PVC no ka hoʻonani o loko , Ke nānā aku nei nā ʻenekinia i ka helu ʻana o ka uahi (SDR) ma lalo o ASTM E662; ʻO kahi SDR haʻahaʻa e hōʻoia i ka ʻike i ka wā o ka haʻalele ʻana. ʻAʻole like me nā lau i hoʻonui ʻia, ka kaʻina hana co-extrusion no ka palekana ahi hana i ka ʻili paʻakiki a ʻoʻoleʻa e hana ma ke ʻano he pale kino, e hoʻopaneʻe maikaʻi i ka decomposition thermal o ka mea kumu.

ʻIkepili Kemika o nā Lead-Free Stabilizers a me RoHS Compliance

ʻO ka hoʻololi i ka ke alakaʻi-ʻole PVC co-extruded pahu pahu ke alakaʻi ʻia nei e nā kuhikuhi kaiapuni honua e like me RoHS (Restriction of Hazardous Substances) a me REACH. Hoʻololi ʻia nā stabilizers kumu alakaʻi kuʻuna me nā mea hoʻokūpaʻa calcium-zinc (Ca-Zn) no ka extrusion PVC , e hōʻoiaʻiʻo ana i ka mea metala kaumaha ma nā papa PVC noho ma lalo o 100 ppm. No ka mea He aha nā kūlana alakaʻi ʻole no nā mea kūkulu hale , ʻo ka manaʻo nui i ka pale ʻana i ka leaching o nā mea neurotoxic i loko o ke kaiapuni. Hoʻohana ʻo Jiatao Industrial i ka paʻa hoʻomaha maikaʻi e hoʻopaʻa i ka polimer matrix, e hōʻoia i ka ʻO ke kūpaʻa UV o ka PVC kepau-ʻole mālama ʻia me ka hōʻole ʻole ʻana i ka paʻa o ke kino. ʻO kēia ʻenehana papa pahu pahu PVC ʻona ʻole He mea koʻikoʻi ia no ka ʻoihana lako a me nā kaʻa kaʻa i loko o ka lehulehu, kahi e launa pinepine ai ke kanaka a lōʻihi.

Hoʻohālikelike Hoʻohālikelike Kūʻai a me nā Waiwai Mechanical

A pvc co-extruded foam papa ʻike ʻia e kona ʻano "sandwich", ʻo ia hoʻi me kahi pūpū o waho kiʻekiʻe a me kahi pahu pahu pani pani. ʻO ka paʻakikī o ka ʻili o ka PVC i hoʻokuʻu ʻia ʻoi aku ka maʻamau ma mua o 75 Shore D, e hāʻawi ana i ke kūpaʻa ʻoi aku ka maikaʻi e hoʻohālikelike ʻia me nā celuka a i ʻole nā ​​mea ʻokoʻa manuahi. ʻO ka ikaika tensile o nā papa PVC hale he hana ia o ka ikaika paʻa co-extrusion ma waena o ka ʻili a me ke kumu. Hāʻawi ka papa ma lalo i kahi hoʻohālikelike ʻenehana o ka hana mechanical e pili ana i nā kūlana hoʻāʻo ISO a me ASTM.

ʻO ka hana Hydrophobic a me ke kū'ē i ka hoʻohaʻahaʻa kino

ʻO ka hana wai ʻole o ka papa ʻōhua i hoʻokuʻu ʻia ʻoi aku ka maikaʻi ma muli o kona papa waho ʻole porous, kahi e kaupalena ʻia ai ka hoʻoheheʻe ʻana o ka wai ma lalo o 0.5 pakeneka e like me ISO 62. Ke pale nei kēia i ka ka hoʻopaʻa ʻana o ka papa PVC ma nā wahi haʻahaʻa , e lilo ana ia i mea hoʻololi kūpono i nā hui lāʻau plastik i loko o ka hana kai a me waho.

FAQ paʻakikī ʻoihana

Q1: Ua pili anei ka inoa "lead-free" i ka ikaika mechanical o ka papa?
A1: ʻAʻole. ʻOiai e koi ana nā stabilizers Ca-Zn i ka mana o ka wela i ka wā extrusion, hiki i ka papa hopena ke loaʻa i ka modulus flexural like a ʻoi aʻe paha a me ka ikaika o ka hopena i hoʻohālikelike ʻia me nā huahana paʻa kepau.

Q2: Hiki ke hoʻokō ʻia ka helu ahi V-0 no nā mānoanoa āpau?
A2: ʻO ka maʻamau, ʻoi aku ka maʻalahi o ka loaʻa ʻana o nā helu V-0 ma nā papa mānoanoa (10mm). No nā ʻāpana lahilahi (3mm-5mm), pono nā pūʻolo hoʻohui kūikawā e hōʻoia i ka ʻaʻa ʻole o ka mea i loko o ka paepae 10-kekona.

Q3: He aha ka pono o ka co-extrusion ma luna o Celuka foam papa?
A3: Hoʻopuka ka hui hoʻokuʻi ʻana i kahi ʻili paheʻe, ʻoi aku ka paʻakikī me ka palena ʻoi aʻe ma waena o ka ʻili ʻeleʻele a me ke kumu o ka huʻa, ʻoiai ʻo ka ʻili Celuka he ʻoi aku ka gradient mānoanoa a ʻoi aku ka maʻalahi i nā hemahema o ka ʻili.

Q4: Pehea e hōʻoiaʻiʻo ai ʻo Jiatao i ka 25,000-ton ka hoʻopuka makahiki e mālama i ka maikaʻi?
A4: Hoʻohana mākou i nā ʻōnaehana dosing automated a me nā naʻau nānā mānoanoa manawa maoli ma ka laina extrusion e hōʻoia i ka paʻa a me ka hoʻohui kemika e mau i kēlā me kēia pūʻulu.

Q5: Hiki ke hoʻohana hou ʻia ka PVC co-extruded foam board?
A5: ʻAe. Ma ke ʻano he thermoplastic, hiki ke hoʻoneʻe ʻia a hana hou ʻia. No ka mea, ʻaʻohe alakaʻi a me RoHS ko mākou papa, ua waiwai nui lākou i ka ʻoihana pōʻai i hoʻohālikelike ʻia i nā kahawai ʻōpala i hoʻohaumia ʻia.
