He pale wai ka PVC?
He pale wai ka PVC?
Ma ke ʻano he kanaka kahiko i hala i nā makahiki he ʻumi ma ka ʻoihana PVC, hiki iaʻu ke haʻi me ka mana: ʻAʻole wai wai wale ka PVC-ʻo ia kekahi o nā kumu kūʻai ʻoi loa-pono a hilinaʻi hoʻi i ka wai wai. ʻO kona hiki ke hoʻokuʻu i ka wai i hoʻopaʻa ʻia ma ka pae molekala, e lilo ia i mea ikaika ma waena o nā ʻoihana, mai ke kūkulu ʻana i nā mea kūʻai aku.
E luʻu hohonu kākou i ka ʻepekema, nā noi, a me nā ʻoiaʻiʻo pono e pili ana i ka wai wai PVC.
ʻO ka ʻepekema kumu: no ke aha e hiki ʻole ai i ka wai ke paʻi i ka PVC
Hoʻokumu ʻia ka hiki wai o PVC mai ʻekolu mau ʻano kumu:
Hoʻonaʻauao Molekuʻi
Hoʻokumu nā polymers PVC i nā kaulahao paʻa, -porous ʻole i waiho ʻole i ke ala e komo ai nā mole wai. E noʻonoʻo ʻoe he pā paʻa-ka wai hiki ʻole ke komo.
ʻO ka Hydrophobicity
Kūleʻa kemika ʻo PVC i ka lawe ʻana i ka wai a ʻaʻole pehu a hoʻohaʻahaʻa i ka wā e ʻike ʻia ai i ka makū, ʻoiai i nā manawa lōʻihi.
Hoʻokumu ʻia ʻo Paʻa ʻole
Inā ʻoʻoleʻa (e like me nā paipu) a ʻoluʻolu paha (e like me ka lole PVC), hana nā huahana PVC i hoʻopau ʻia i mau papa impermeable e pale pono ai i ka wai wai.
Kahi e noho aliʻi ai ka pale wai PVC
Mahalo i kāna mau waiwai wai ʻole PVC, ʻo kēia mea ke hele-e koho i nā wahi koʻikoʻi ʻelima:
1. Ke kūkulu 'ana a me ka ho'onanea 'ana i ka wai
Nā Membrane Puʻupuʻu: Hāʻawi nā ʻōnaehana kaupaku PVC hoʻokahi-ply 25+ makahiki o ka hoʻopaʻa wai pono me ka UV maikaʻi loa a me ke kū ʻana i ka wā.
Geomembranes: Hoʻohana ʻia i loko o nā pae ʻāina, nā loko, a me nā loko i hana ʻia e pale ai i ka ʻike ʻana a me ka pale ʻana i ke kaiapuni.
2. PVC Tarpaulin a me na uhi pale
ʻO kēia kahi e ʻālohilohi ai nā ʻano wai wai o PVC. Ma ka ho'oikaika 'ana i ka polyester mesh me ka uhi PVC, loa'a iā mākou ka Polyester PVC-he mea 100% wai 'ole, waimaka-ku'e, a pa'a. ʻO ia ke koho kiʻekiʻe no nā uhi kaʻa, nā tarps mālama, nā hale lole, a me ka pale ʻana i nā lako hana.
3. Pūnaehana Paipu
ʻO nā paipu PVC e hoʻomalu i ka lako wai a me nā ʻōnaehana hoʻoheheʻe no ka mea e hōʻoiaʻiʻo lākou i ka zero permeability i ko lākou ola holoʻokoʻa, e pale ana i nā leaks a me ka pale ʻana i nā ʻōnaehana.
4. Mea kūʻai maʻalahi a me nā lako pale
Nā lole ua a me nā lole pale: Hāʻawi ka lole PVC palupalu i ka wai piha i nā ʻaʻahu ua, nā lole hana, a me nā kāmaʻa.
ʻO nā Liners Pool: ʻO nā liner PVC ka hopena hilinaʻi loa no nā loko noho a me nā loko pāʻoihana, e hāʻawi ana i ka -pale leak no ka manawa lōʻihi a me ka lōʻihi.
5. Na Lako waho & Lako
Mai nā noho kīhāpai a hiki i nā uhi mīkini, pale ke ʻano wai ʻole o PVC i ka ua a me ka makū, pale i ka ʻōpala a hoʻolōʻihi i ke ola o ka huahana.
Nā palena ʻoiaʻiʻo: He aha ka PVC hiki ʻole ke hana
ʻAʻohe mea kūpono. No ka hoʻohana pono ʻana iā PVC, e hoʻomaopopo i kona mau palena:
Heat Sensitivity: Hiki ke hoʻopalupalu a me ka deformation ka lōʻihi ma luna o 70 degere (158 degere F). E hō'ole i ka ho'ohana 'ana i ka PVC no ka ho'ohana 'ana i ka wela ki'eki'e (e la'a, nā paipu wai wela).
ʻAʻole hiki ke hoʻoheheʻe ʻia i ka wai, nā waikawa, a me nā alkali, hiki ke hōʻino ʻia ka PVC e nā mea hoʻoheheʻe organik ikaika e like me nā ketones a i ʻole kekahi mau esters. E nānā mau i ka hoʻohālikelike kemika no nā hoʻohana ʻoihana.
Seam-Hana Hana: No nā lau nui e like me ka PVC tarpaulin a i ʻole ka uhi o ka hale, pili ka pono o ka wai i ka wili wili a i ʻole ka maikaʻi o ka hoʻopaʻa ʻana. He mea koʻikoʻi ka hoʻokomo pono ʻana.
ʻO ka wā e hiki mai ana o PVC i ka pale wai
Ma waena o ka ulu ʻana o nā koi no ka hoʻomau, ke ulu nei ka ʻoihana PVC. ʻO nā mea hoʻopaʻapaʻa manuahi, -pilikia kaiaola, a me nā ʻenehana hana hou i kēia manawa. Hoʻohālikelike ʻia me nā mea ʻē aʻe e like me TPO a i ʻole EPDM, mālama ʻo PVC i nā pōmaikaʻi ikaika i ka nui o ke kumukūʻai, ka moʻolelo i hōʻoia ʻia, ka maʻalahi o ka hana ʻana, a me ka ʻikepili hana i nā makahiki he mau makahiki.
Ka hopena: No laila, ʻo PVC Waterproof?
ʻAe, ʻae.
ʻO PVC ka manawa-i hoʻāʻo ʻia, akamai i ka waiwai, a me ka pono wai ʻole. Mai nā papahana hoʻonaʻauao nui a hiki i ka ʻahu ua i loko o kou keʻena keʻena, hāʻawi ʻo PVC i ka palekana hilinaʻi mai ka wai, i kākoʻo ʻia e ka ʻepekema a me ka hana maoli-honua honua.
Ke makemake ʻoe i kahi mea wai ʻole e kaulike ana i ka hana, ka lōʻihi, a me ke kumukūʻai, noho mau ʻo PVC i mea hakakā kaumaha.
