Ua liloʻo PVC SHARING SHARPS i lilo i punahele punahele o ka puka o ka pukaʻana a me nā puka aniani e hōʻailona ana i nā kaula no ka meaʻaʻole lākou e maʻalahi i ka weld. Akā he 2-3 mau makahiki wale nō,ʻikeʻia ka pilikia. ʻO ka hoʻokaʻawaleʻana o nā pepa pvc, kahi pilikiaʻoihana paʻakikī paʻakikī, ua hōʻike maoliʻia ma nā kiʻi snaling pvc.
Ma muli o ka hoʻokaʻawaleʻana o ka palaki, ua hoʻohaumiaʻia kaʻaoʻao o ka'ōpala, ua pōkole ka nui o ka pale, a me nā pilikia o kaʻokiʻoki. Eia nō naʻe,ʻo ka laweʻana i nā mea kūʻai aku-Sponedal School ʻO ka hopena o ka helu PVC SENATING TRAPP e hoʻomaka ana eʻike.
EPDM EPDM SILDM SURPS i ka wā o 2000, ua hoʻopuka ka'āina i kahi papa inoaʻo PVC e EPDM EPDM SELINING CHARP, kahi hōʻailona kiʻekiʻe kiʻekiʻe i hoʻohanaʻia ma nā kaʻa a me nā kaʻa, ua hāpaiʻia e kaʻoihana kūkulu.
I kaʻoiaʻiʻo, ua nui ka hoʻohanaʻia ma ka puka a me nā puka makani me ka makahiki 2002. I kēlā manawa, ua komo mau nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka a me nā puka. Ua liloʻo EPDM i ka synnymous me nā hōʻailona hōʻailona kiʻekiʻe ma muli o kāna mau mea pilikino maikaʻi loa a me ke kū'ē maikaʻiʻana. Ma ka 2011, ua loaʻa ma nāʻanuʻu e nā mea komo a me nā mea'ē aʻe, ua hele mai ka lole o Epodm. He paʻakikī nā hōʻailona maikaʻi e hele mai. Puka makani a me ka puka aniani sealing strip strip Aia kekahi luna ma ka hana like ma kēia kalana, a me 70% o ka'āina o keʻano o ka'āina e hele mai ana mai US.
ʻO Silicone Rule Slack Slack Sleepyʻaʻole nui loa i ka mea hou loa no nā hōʻailona hōʻailona,ʻaʻole ia. ʻO Silicone Rudber kahi moʻolelo o nā makahiki he mau makahiki ma Kina. ʻO ka puka aniani a me nā puka aniani e hōʻailona ana i nā mea hana crip srip i nā manawa ma mua I nā makahiki i hala iho nei, ua emi iki ke kumukūʻai, a ua noi koke lākou i nā hōʻailona kūkulu.
Hoʻohālikelikeʻia me ka coppyne-propylene-propylene, ka maikaʻi o ka silicone rubber, no laila eʻoi aku ka maikaʻi o keʻano o ka manawa. ʻO ka'ōpala ma ka maikaʻi loa 180 ° C. Ma lalo o keʻano like me keʻano o keʻano o Silicone Rubber eʻelua mauʻelua o Estlenene Compplene Rubber A uaʻoi aku ka maikaʻi o ka maʻi lapaʻau psyrialogical,ʻaʻoleʻo Silima,ʻo Silini Stoping i + 250 ° C (a iʻole ke kiʻekiʻe kiʻekiʻe). He koho maikaʻiʻo Silicone no ke koho kūpono no ka hale kūkulu hale i ka wā o kēia manawa.
