Anawaena inoa: 63mm-630mm
Ka helu kaomi: 0.2Mpa, 0.25Mpa, 0.32Mpa, 0.4Mpa
Hiki ke kūpono: He kūpono no ka hoʻoheheʻe wai paipu haʻahaʻa haʻahaʻa, hoʻoheheʻe wai, hoʻokahe a me nā papahana ʻē aʻe o ka hoʻouna ʻana a me ka hoʻolaha pūnaewele.
Pāhana kūpono: 0-45 ℃
ʻO ke ʻano hoʻohui: Me ke ʻano o ka solvent type adhesive a me ka elastic sealing ring type (ʻo ia hoʻi ke ʻano pāpaʻa a me ke ʻano kumu R).
Ua hoʻokumu ʻia ʻo Dayu Water Saving Group Co., Ltd. ma 1999. He ʻoihana ʻenehana kiʻekiʻe ia e pili ana i ka Chinese Academy of Water Science, ka Science and Technology Promotion Center o ke Kuhina Waiwai, ka Chinese Academy of Science, ka Chinese Academy of Engineering a me nā keʻena noiʻi ʻepekema ʻē aʻe.Kau ʻia ma ka Growth Enterprise Market.Kānāwai waiwai: 300021. Ua hoʻokumu ʻia ka hui no 20 mau makahiki a ua hoʻomau mau a hoʻolaʻa iā ia iho i ka hoʻonā a me ka lawelawe ʻana o ka mahiʻai, nā wahi kuaʻāina a me nā kumu wai.Ua hoʻomohala ʻia i loko o kahi hōʻiliʻili o ka mālama wai mahiʻai, ka lako wai o ke kūlanakauhale a me ke kua'āina, ka mālama ʻana i ka wai, nā hana wai akamai, ka pili ʻana o ka ʻōnaehana wai, ka hoʻokele kaiaola wai a me ka hoʻihoʻi ʻana a me nā māla ʻē aʻe.He mea hoʻolako ʻōnaehana ʻoihana no ke kaulahao ʻoihana holoʻokoʻa e hoʻohui ana i ka hoʻolālā papahana, hoʻolālā, hoʻopukapuka, kūkulu, hana, hoʻokele a me nā lawelawe mālama.ʻO ia ka mua o ka ʻoihana ma ke kahua o ka mālama wai mahiʻai ma Kina a he alakaʻi honua.
ʻO UPVC, i kapa ʻia ʻo PVC paʻakikī a i ʻole PVCU, ua haku ʻia me kahi resin thermoplastic amorphous i hana ʻia e ka polymerization o ka vinyl chloride monomer a me kekahi mau mea hoʻohui (e like me nā stabilizers, lubricants, fillers, etc.).Ma kahi o ka hoʻohana ʻana i nā mea hoʻohui, hoʻohana ʻia ke ʻano o ka hui ʻana me nā resins ʻē aʻe i mea e maopopo ai ka waiwai kūpono.ʻO kēia mau resins he CPVC, PE, ABS, EVA, MBS a pēlā aku.Loaʻa i ka UPVC ka viscosity hoʻoheheʻe kiʻekiʻe a me ka wai maikaʻi ʻole.ʻOiai inā e hoʻonui ʻia ke kaomi injection a me ka wela heheʻe, ʻaʻole e loli nui ka wai.Eia kekahi, ua kokoke loa ka mahana hoʻoheheʻe ʻana o ka resin i ka wela decomposition thermal, a ʻo ka laulā wela e hiki ke hoʻoheheʻe ʻia he haiki loa, e lilo ia i mea paʻakikī.
Nā hiʻohiʻona:
1. ʻO ke kaumaha māmā, kūpono e mālama a wehe i ka ukana:
He māmā loa ka mea o ka paipu PVC, he mea maʻalahi ke hana a hana, a hiki ke mālama i ka hana.
2. Paipai kemika maikaʻi
ʻO ka paipu PVC he kūpaʻa maikaʻi loa ka waika, ke kūpaʻa alkali, a me ke kūpaʻa corrosion, kahi kūpono loa no ka hoʻohana ʻana i ka ʻoihana kemika.
3. Li'ili'i wai kū'ē
He laumania ka ʻili o ka pā o ka paipu PVC, a he liʻiliʻi ke kūʻē i ka wai.ʻO 0.009 wale nō ka helu o kona ʻāʻī, ʻoi aku ka haʻahaʻa ma mua o nā mea paipu ʻē aʻe.Ma lalo o ke kahe kahe like, hiki ke hoʻemi ʻia ke anawaena paipu.
4. Ka ikaika mechanical kiʻekiʻe
ʻO ke kūpaʻa o ka wai, ka pale ʻana i waho a me ka pale ʻana i ka hopena o nā paipu PVC he maikaʻi loa ia, a he kūpono ia no nā papahana paipu ma lalo o nā kūlana like ʻole.
5. Hoʻopili uila maikaʻi
ʻO ka paipu PVC maikaʻi loa ka insulation uila a kūpono i nā conduits o nā uea a me nā kaula, a me nā paipu uea i nā hale.
6. ʻAʻole pili i ka maikaʻi o ka wai
Hōʻike ka ho'āʻo hoʻoheheʻe ʻana ʻaʻole pili ka paipu PVC i ka maikaʻi o ka wai, a ʻo ia ka mea paipu maikaʻi loa no ka paipu wai i kēia manawa.
7. Hana maʻalahi
He wikiwiki a maʻalahi ka hana hui ma waena o nā paipu PVC, no laila he haʻahaʻa ke kumukūʻai ʻenehana
