ʻO nā ʻokoʻa ma waena o PVC a me PVC olakino

He aha ka PVC? ʻO PVC ka pōkole o polyvinyl chloride (PolyvinylChloride), he mea make ole, pauda keʻokeʻo ʻole. He kiʻekiʻe kemika ko PVC, maikaʻi plasticity a me ka maikaʻi loa uila insulation. PVC lapaau (polyvinyl chloride) he resin thermoplastic polymerized e ka vinyl chloride ma lalo o ka hana a ka mea hoʻomaka a hoʻohana nui ʻia i nā lāʻau lapaʻau a me nā mea lapaʻau.. ʻO ka PVC lapaʻau he ikaika mechanical maikaʻi, biocompatibility, non-toxic, kalai maʻalahi, paʻa kemika maikaʻi, pale anu, pale ʻana i ka radiation a me ka hoʻokaʻawale uila maikaʻi.

E aʻo hou e pili ana i ka PVC olakino?

He aha ke ʻano o ka pvc ma nā ʻōlelo lapaʻau?
Ma nā ʻōlelo lapaʻau, Kū pinepine ʻo PVC no ka ʻoki ʻana o ka ventricular premature. E pili ana kēia i ka puʻuwai puʻuwai maʻamau i hana ʻia e ka hoʻāla ʻana o ka ventricles, ka mea e hoʻopilikia i ka puʻuwai maʻamau. ʻAʻohe pōʻino maʻamau ka PVC, aka, ina e puka pinepine ia, he hōʻailona paha ia o ka maʻi puʻuwai.

ʻO ka PVC no ka hoʻohana olakino he mea ia, ʻokoʻa loa ia mai ka pvc ke ʻano o ka lāʻau lapaʻau. Hoʻohana nui ʻia ka PVC lāʻau lapaʻau e hana i nā mea hoʻopihapiha no nā mea lapaʻau a me nā mea lapaʻau. ʻo kahi laʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea hana no nā mea lapaʻau e like me nā paipu infusion, catheters, a me na kui kui. Pono kēia mau lāʻau lapaʻau e loaʻa ka biocompatibility maikaʻi a me ka paʻa kemika e hōʻoia i ka palekana a me ka pono i ka wā e hoʻohana ai.

lāʻau pvc

Nā pono lapaʻau o ka lāʻau PVC

PVC lāʻau, ʻo ia, lāʻau lapaʻau polyvinyl chloride (Polyvinyl chloride) mea waiwai, loaʻa nā pōmaikaʻi koʻikoʻi ma ke kahua o ka hoʻopili lāʻau lapaʻau.

Na waiwai kino maikai o lāʻau PVC

ʻAʻahu i ke kū'ē a me ka waimaka: ʻO nā mea PVC lāʻau lapaʻau maikaʻi ke kūpaʻa a me ka waimaka, ʻo ia ka mea hiki ke pale pono i ka pōʻino i ka ʻeke i ka wā o ka lawe ʻana a me ka mālama ʻana, e hōʻoiaʻiʻo ana i ka pono o ka lāʻau lapaʻau.
ʻO ke kū'ēʻana a me ka hopena: Loaʻa i nā mea PVC ke kūpaʻa hoʻopiʻi maikaʻi loa a me ke kūpaʻa hopena, hiki ke mālama i ke kūpaʻa o kona ʻano a me kona ʻano ma nā ʻano like ʻole, pale hou aku i nā lāʻau mai ke kaomi o waho a i ʻole ka hopena.
ʻO ka maʻalahi a me ka ikaika pelu: Loaʻa i nā pepa PVC ka maʻalahi a me ka ikaika pelu, a hiki ke pale i ka extrusion a me ka deformation mai nā mana o waho, e hōʻoia i ka paʻa mau ʻana o nā lāʻau lapaʻau a me ka haumia ʻole i ka wā o ka hoʻopaʻa ʻana a me ka hoʻohana ʻana.

Paʻa kemika maikaʻi

ʻAkika a me ka alkali pale: He kūpaʻa ikaika ka mea PVC i nā mea lāʻau lapaʻau maʻamau e like me nā waikawa a me nā alkalis, a hiki ke pale maikaʻi i nā hopena kemika ma waena o nā lāʻau lapaʻau a me nā mea paʻi, e hōʻoiaʻiʻo ana i ke kūpaʻa kemika o nā lāʻau.
ʻO ke kūpaʻa ʻana a me ka pale ʻana i ka corrosion: ʻO nā mea PVC hoʻi he maikaʻi ke kūpaʻa oxidation a me ke kūpaʻa corrosion, a hiki ke pale aku i ka erosion o oxidants, mea hoemi a me na mea e ae, e hooloihi ana i ke ola o na laau lapaau.

Biocompatibility

Hoʻohana nui ʻia nā mea PVC i ka ʻoihana olakino, e like me ka hoomakaukau ana i na paipu, ʻeke infusion a me nā mea lapaʻau ʻē aʻe a me nā mea hana e pili ana i ke kino kanaka. ʻO kēia ma muli o kona biocompatibility maikaʻi, ʻo ia, ʻAʻole e hoʻoulu ʻia nā mea PVC i nā hopena maʻi a i ʻole nā ​​​​hopena ʻino ʻē aʻe i ke kino o ke kanaka, pēlā e hōʻoia ai i ka palekana a me ka hilinaʻi o nā lāʻau i ka wā e hoʻohana ai.

Maʻalahi ka hana a me ke kumu kūʻai haʻahaʻa

Maʻalahi e hana a hoʻoheheʻe: ʻO ka mea PVC he plasticity maikaʻi a me ka processability, a hiki ke hana maʻalahi i nā ʻano hana like ʻole a me ka hoʻoheheʻe ʻana, e like me ka extrusion, hoʻoheheʻe ʻia, etc., ma laila e hoʻokō ai i nā pono like ʻole o ke kahua paʻi lāʻau lapaʻau.
Kumukuai haahaa: Hoʻohālikelike ʻia me nā mea hoʻopihapiha hana kiʻekiʻe, ʻO nā mea PVC he haʻahaʻa koina hana, hiki ke mālama i nā kumukūʻai a hoʻomaikaʻi i nā pono waiwai no nā hui lāʻau lapaʻau.

Laulā o nā noi

Hoʻohana nui ʻia nā mea PVC lāʻau lapaʻau ma ke kahua o ka lāʻau lapaʻau ma muli o nā pono i luna, e like me ka blister packaging, lepili omole laau, sila a me na eke laau lapaau, etc. ʻAʻole hiki i kēia mau palapala hoʻopili ke pale pono i nā lāʻau mai ke kaiapuni o waho, akā e hoʻomaikaʻi pū i ka maʻalahi o ka mālama ʻana, ka lawe ʻana a me ka hoʻohana ʻana i nā lāʻau lapaʻau.

Nā ʻano hoʻohana o ka PVC lāʻau lapaʻau i ka hoʻopili lāʻau

ʻO PVC kahi plastic maikaʻi a maikaʻi me ka ikaika kiʻekiʻe a me ka rigidity, a hiki ke pale pono i ke komo ʻana o ka oxygen a me ka mahu wai. No laila, Hoʻohana pinepine ʻia ʻo PVC ma ke ʻano he substrate i ka hoʻopili lāʻau, a ua hoʻonui ʻia ka waiwai o ka pale ma ka hui ʻana me nā mea pale kiʻekiʻe ʻē aʻe (e like me ka alumini pepa). No laila, Hiki ke hoʻohana nui ʻia ka PVC i ka hoʻopili ʻana i nā huahana lāʻau.

Nā ʻano noi no ka PVC lāʻau lapaʻau (polyvinyl chloride) i loko o ka waihona lāʻau:

Puke pohū

Hoʻohana pinepine ʻia ka hoʻolālā composite PVC / PVDC i ka blister packaging, ʻoi aku no nā lāʻau paʻa e like me nā papa a me nā capsules. Hiki i kēia puʻupuʻu ke hāʻawi i ka pale hoʻokaʻawale kūpono e pale aku i nā lāʻau mai ka hoʻopilikia ʻia e ka ea a me ka makū. Hiki ke hoʻopaʻa ʻia i ka ʻōpala blister a i ʻole i hoʻopaʻa ʻia i ke anu. Hoʻohana pinepine ʻia ʻo PVC i ke kaʻina hana thermoforming me kahi mahana wela ma kahi o 100 ℃ a 150 ℃..

pharmaceutical blister packaging

Puke ʻāpana ʻāpana

He mea maʻalahi ke ʻoki ʻia nā mea PVC/PVDC a hiki ke hoʻolālā ʻia i loko o ka paʻi kūʻokoʻa o hoʻokahi dosis a hoʻokahi blister., He mea maʻalahi ia no nā poʻe maʻi e lawe i ka wā e hoʻohana ai a hoʻemi i ka pau ʻana o ka lāʻau.

Puke lāʻau kūikawā kūikawā:

No nā lāʻau lapaʻau e pili ana i ka wai, oxygen, etc., e like me nā lāʻau lapaʻau, nā huaora, nā capsules kūikawā, etc., Hiki i nā mea PVC / PVDC ke hāʻawi i ka palekana maikaʻi loa.

ʻEke Infusion

Hoʻohana ʻia ʻo PVC e hana i nā ʻeke infusion olakino. Ua hōʻike ʻia nā haʻawina ʻo ka hoʻohui ʻana i ka organotin hiki ke hoʻomaikaʻi i ka ʻike a me ka hoʻoili ʻana i ka wai o nā ʻeke infusion PVC olakino.

Nā ʻāpana palaki no ka hoʻopili lāʻau

E like me ka hoʻohui waiwai, ʻO PVC kekahi o nā mea maʻamau i hoʻohana ʻia no nā ipu plastik a me nā ʻāpana no ka hoʻopili lāʻau, a hiki ke hoʻohana ʻia e hana i nā ʻāpana plastik e like me nā uhi a me nā pilina.

ʻO nā mea i luna aʻe kekahi o nā ʻano noi nui o ka PVC lāʻau lapaʻau i loko o ka pahu lāʻau lapaʻau, ka mea e hoʻohana i nā ʻano o nā mea PVC, e like me nā mea pale, ka ikaika mechanical a me ka hana hana, e hōʻoia i ka maikaʻi a me ka palekana o nā lāʻau lapaʻau.
