Daya, PVC kumfa allon gabatarwa
PVC kumfa jirgin kuma aka sani da dusar ƙanƙara jirgin ko Andy board, bisa ga samar da tsari, bayyanar da yi za a iya raba PVC kumfa jirgin da free kumfa jirgin.
PVC fata kumfa jirgin ne samar da Celuca tsari, tare da wani Layer na wuya fata a kan surface, santsi da kuma santsi, high taurin, mai kyau inji Properties, da kuma high daidaici kayayyakin, kananan kauri kuskure, m buƙatun a kan mold, dabara, tsari da kuma raw. kayan aiki.
Filayen allon kumfa na kyauta na PVC yana kwance, babu ɓawon burodi, kuma saman yana da kyau kuma yana da kyau, wanda ya dace da bugawa, fesa da veneering.Ana iya samar da shi ta hanyar ƙirar kumfa na yau da kullun, kuma tsarin yana da sauƙin sarrafawa.
Biyu, halaye na allon kumfa na PVC
Practice ya tabbatar da cewa PVC kumfa jirgin yana da kyau thermal rufi, zafi kiyayewa, sauti rufi, haske hali da sauran kaddarorin, fiye da sauran haske m filastik kumbura perlite, ceramsite, asbestos kayayyakin da sauran rufi kayan, yana da halaye na sauki aiki, high high. digiri na injiniyoyi, adana lokaci, ceton aiki.PVC kumfa jirgin za a iya hawa ta inji a tsaye bututun, wanda shortens da aiki lokaci da kuma inganta yadda ya dace da 6 ~ 10 sau idan aka kwatanta da sauran hanyoyi.
PVC kumfa jirgin sanya rufi Layer, amfani da rufin rufi da kuma waje bango rufi, yana da m thermal rufi yi da mannewa yi ga tsarin Layer, da kuma dace yi, kare muhalli, lokaci ceto, yadda ya dace da kuma sauran abũbuwan amfãni, za a iya amfani da su maye gurbin. polystyrene (kwatin benzene) da sauran kayan rufin zafi.Hakanan ana amfani da allon kumfa na PVC a yankin kudu don yin tubalin kumfa na PVC, don cimma manufar rufin rufin da rufin bangon waje.Yana da fasali kamar haka:
1) Tattalin Arziki: ƙananan farashi.
2) Thermal rufi: thermal watsin ne 0.06-0.070W/ (MK), da thermal juriya ne game da 10-20 sau na talakawa kankare.
3) nauyi: bushe girma yawa na 200-300kg / M3, daidai da game da 1/5 ~ 1/8 na talakawa ciminti kankare, na iya rage overall load na ginin.
4) Ƙarfin ƙwaƙwalwa: Ƙarfin ƙwaƙwalwa shine 0.6-25.0MPA.
5) Mutunci: na iya zama wurin zubar da ginin, a hade tare da babban aikin, babu buƙatar barin iyakar iyaka da bututun iska.
6) low na roba girgiza sha: da porosity na PVC kumfa jirgin sa shi da low na roba modulus, sabõda haka, yana da kyau sha da watsawa sakamako a kan tasiri load.
7) Simple yi: kawai amfani da PVC kumfa jirgin inji iya gane atomatik aiki, iya gane a tsaye tsawo na 200 mita na dogon-nesa sufuri, da aikin ne 150-300m3 / aiki rana.
8) Sauti rufi: PVC kumfa jirgin rufi jirgin ya ƙunshi babban adadin masu zaman kansu kumfa, da uniform rarraba, sauti sha iya aiki na 0.09-0.19%, shi ne 5 sau na talakawa kankare, tare da tasiri sauti rufi aiki.
9) Juriya na ruwa: kwamitin kumfa na PVC da aka jefa yana da ƙananan shayar ruwa, kumfa masu zaman kansu masu zaman kansu da kuma kyakkyawan mutunci, don haka yana da wani aikin hana ruwa.
