1. Noi a me ka hoʻomākaukau pōkole:
Hoʻohana nui ʻia ka mea kūikawā o ka uhi polypropylene no ka uhi ʻana o ka ʻeke ʻeke polypropylene a me ka lole i ulana ʻia. Ma hope o ka uhi ʻana, hiki ke hoʻohana pololei ʻia nā ʻeke i ulana ʻia me ka ʻole o ka uhi ʻana i nā ʻeke polyene. ua hoʻomaikaʻi ʻia ka ikaika a me ka hana holoʻokoʻa o ka ʻeke i ulana ʻia no ka mea ua uhi pono ʻia ka polypropylene circulation film ma ka ʻeke i ulana ʻia, a ua maʻalahi ka hoʻohana ʻana, a ua hoʻemi ʻia ke kumukūʻai hana.

Ua hoʻokumu ka State Building Materials Agency (National Building Materials Bureau) i nā huaʻōlelo & lt;1997>No.079 i Nowemapa 1997, e ʻōlelo ana e hoʻohana ʻia nā ʻeke i ulana ʻia no ka hoʻopili ʻana i ka sima a me nā huahana ʻē aʻe. I ka manawa like, me ka hoʻomohala ʻana o ka ʻoihana hoʻopihapiha kūloko, ua hoʻonui nui ʻia ka hoʻohana ʻana a me ke ʻano o ka pena pena PP. Ua kūʻai ka mea hana ʻilika kumu i ka laina hana o nā ʻeke ʻeke a me nā ʻeke i ulana ʻia, ua hoʻololi ʻia mai ka ʻeke PE i loko o ka ʻeke PP i ulana ʻia i ʻelua ʻeke uhi uhi a me ʻekolu-i-hoʻokahi ʻeke pepa i hoʻohui ʻia, a me ke koi mākeke o ka papa. Ke piʻi nei ka PP i kēlā me kēia lā. Paʻa paʻa ka hāʻawi ʻana i ka papa pena pena PP.
hāʻawi ʻia i luna, ua hoʻokumu mākou i ka T30S maʻamau a me 2401 (MFR = 2 ~ 4 g / 10min) a ua hoʻomohala maikaʻi i nā mea kūikawā o ka papa uhi (MFR = 20 ~ 32 min, ikaika tensile 24.0 MPa) ma o ka hoʻohaʻahaʻa ʻia ʻana ma hope o ka hui ʻana.

I ka wā o ka hoʻomohala ʻana, ua lawe ʻia kekahi mau hoʻokolohua ma ke koho ʻana i nā mea hoʻoponopono paona molecular a me nā mea ʻē aʻe, ka hui ʻana a me ka plasticizing o nā mea maka a me nā ʻāpana kaʻina pili. Ma hope o ka nānā ʻana i hoʻopaʻa ʻia, ua hoʻoholo ʻia ka hoʻokumu ʻana a me ke kaʻina hana o nā uhi PP. hana i laina hana nui. Ua loaʻa nā hopena ʻoluʻolu ma o nā noi he nui, e hōʻike mau ana i ka maikaʻi paʻa o ka huahana, ka wai hoʻoheheʻe maikaʻi, ka hoʻokumu ʻana o ke kiʻi ʻoniʻoni, ka haʻahaʻa haʻahaʻa, ka ikaika peel kiʻekiʻe a me ka hoʻopili kiʻekiʻe. 2. nā pono waiwai i manaʻo ʻia:

ʻO ke kumukūʻai o nā mea kūikawā no ka ton o ka uhiʻana he 2,000 yuan ka kiʻekiʻe ma mua o ke kumukūʻai o nā mea maka. Ma hope o ka unuhi ʻana i nā lako, nā hana, nā pono hana, ka hoʻohaʻahaʻa ʻana i ka mīkini a me nā lilo ʻē aʻe o 150 yuan, ʻo ka loaʻa kālā ma ka ton o nā mea kūikawā he 1500 yuan. ʻO ka puka makahiki o ka laina hana (helu ʻia e ka extruder me ke anawaena screw o 65) he 350-450 tons, a hiki i ka ʻauhau ʻupena makahiki ke piʻi aku ma mua o 500000 yuan. inā ʻoe e hoʻohana i kahi extruder screw nui, ʻoi aku ka kiʻekiʻe o ka huahana. I kēia manawa, aia ʻo Kina ma mua o 1000 mau ʻeke ʻeke nui, nā kauhale a me nā kūlanakauhale a me nā ʻoihana pilikino he nui. Loaʻa i ka papahana nā manaʻo ākea.
ʻO ka lua, ʻo ka ʻenehana hoʻomākaukau o ka polypropylene cooling masterbatch polypropylene cooling masterbatch he polypropylene-based masterbatch, i hoʻohana nui ʻia e hoʻemi i ka mahana o ka polypropylene spinning a me nā huahana plastik i ka hana ʻana, ʻoi aku ka maikaʻi o ka polypropylene spinning hopena maikaʻi loa, akā hoʻohana pū ʻia i ka hana ʻana o ka polypropylene puhi. ʻO nā kiʻiʻoniʻoni, nā ʻeke lole, monofilament, nā huahana hoʻoheheʻe i loaʻa i nā hopena maikaʻi.
papa kuhikuhi hana nui: hoʻohui i ka 1 ~ 5% cooling masterbatch i ka polypropylene resin no ka hana ʻana; hiki ke hoʻokō i kēia mau helu: hiki i nā māka āpau o ka resin polypropylene ke hana i ka fiber denier maikaʻi kiʻekiʻe C a puni. Hiki ke hoemi i ka wela o ka wili a me ka plastic mai 20°C a i 50°CC; hoʻomaikaʻi i ka maikaʻi o ka fiber polypropylene a me nā huahana plastik; hoʻomaikaʻi i ka pono hana; a hoemi i ka pollution kaiapuni.

Ka nui o ka noi: wili polypropylene, puhi kiʻi polypropylene, ʻeke i ulana polypropylene, monofilament
