5 mau ʻano mea no nā mea hoʻohana maʻamau i hoʻohana ʻia i loko o ke keʻena

Pehea ka nui o kāu ʻike e pili ana i nā mea hoʻohana plastik maʻamau i loko o ka hale hana?

Hale Hana Hanamea hoopau, ka mea i hoʻopau nui ʻia i ka wā o nā hoʻokolohua, he ʻokoʻa a ua māhele ʻia i ʻekolu mau ʻāpana: aniani, plastic a me metallic, e like me ka mea i hoʻohana nui ʻia nā plastics ma muli o kā lākou mau waiwai maikaʻi a me ka hoʻoheheʻe maʻalahi.Aia nā mea maʻamau i kēia mau ʻāpana:

1. PE (polyethylene)

ʻOpaque, paʻakikī, kū'ē i kaʻelemakule, māmā ke kaumaha,ʻaʻole leakage, keʻano palupalu, a me ka hanaʻole e like me ka acetone, kaʻakika acetic, a me ka waika hydrochloric, he paʻa a maʻalahi i nā mahana wela.

Mea hoopauo na mea PE i hoohana mau ia:ʻO nā ʻōmole Reagent，Pasteur Pipettes, ʻeke laʻana uwea, ʻeke Blender, ʻeke ʻōpala olakino Autoclavable…

2. FEP (fluorinated ethylene propylene copolymer)

He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a hiki ke hana ma - 85℃~+ 205℃no ka manawa lōʻihi a ma - 200℃~+ 300℃no nā manawa pōkole;He kiʻekiʻe ka ikaika o ka hopena, ke kuʻekuʻe ʻana, ʻokoʻa ka crystallinity me ka wela o ka mālama ʻana i ka wela, a maikaʻi ke kaʻina hana molding;ʻAʻohe mea ʻawaʻawa, ʻaʻole viscous, hoʻokaʻawale uila, pale i ka abrasion, paʻa kemika;Hiki ke waihoʻoluʻu, hiki ke hoʻohana hou ʻia.

maʻamaumea hoopauʻO nā mea FEP he: nā leʻaleʻa hoʻokaʻawale, nā pahu Erlenmeyer, nā paipu centrifuge kiʻekiʻe..

3. PS (polystyrene)

Paʻa, paʻakikī me ke aniani hoʻololi wela ma luna o 100 ° C, paʻa i ka hapa nui o ka wai, akā ua ʻino ʻia e ka nui o nā mea kūlohelohe.

ʻO ka hapa nui o nā mea hoʻohana o ka moʻomeheu cell e hoʻohana i ka PS ma ke ʻano he mea, e like me: Nā kīʻaha moʻomeheu cell, nā kīʻaha Petri, nā ipu moʻomeheu Cell, nā pā moʻomeheu Cell, nā papa Elisa, nā puka Inoculation, Cell spreader, Serological pipettes…

4.PC (polycarbonate)

Loaʻa iā ia ka ikaika kiʻekiʻe a me ka elasticity coefficient, ka ikaika hopena kiʻekiʻe, ʻoi aku ka maikaʻi o ka transparency, ka paʻakikī nui a hiki ke hoʻomaʻemaʻe ʻia i ka wela kiʻekiʻe, akā ʻaʻole ia e ʻae i nā kumu waikawa ikaika a me kekahi mau mea hoʻoheheʻe organik e like me ka waiʻona.

ʻO nā mea hoʻohana o PCmea waiwai:

ʻO Erlenmeyer Flasks, pahu mālama Cryogenic

5.PP (polypropylene)

ʻO ka translucency, ʻoi aku ka maikaʻi o ke kemika a me ka paʻa wela, a ʻoi aku ka paʻakikī o nā lima ma mua o ka PE, hiki ke hoʻohana ʻia ma kahi o 100 degere, akā ma nā haʻahaʻa haʻahaʻa e lilo i palupalu, ʻaʻahu ʻole, ʻelemakule maʻalahi, pale i ka corrosion, a he liʻiliʻi ka hopena o ka waika a me ka alkali. ma luna o laila.

ʻO nā mea hoʻohana o PCmea waiwai:

ʻO nā paipu Centrifuge, nā paipu Cryogenic, ʻO nā paipu Micro (Papa hōʻiliʻili laʻana), nā paipu PCR, nā pā PCR, nā papa hohonu hohonu, nā ʻāpana ʻāʻī, nā ʻōlelo aʻoaʻo Pipette, nā ʻōmole Reagent, nā paipu Extraction…

ʻO Labio ka laina PP a me ka laina PS i kūʻai ʻia ma kahi ʻano nui, kūpaʻa a hilinaʻi maikaʻi, ua hoʻolako piha ʻia nā mea maka a pau me nā mea lāʻau lapaʻau i lawe ʻia mai, e hōʻoiaʻiʻo ana i nā waiwai physicochemical maikaʻi o nā huahana, a, mau, kahi kumu o ka ʻoluʻolu. nā huahana a me nā lawelawe no nā mea kūʻai aku a me nā hoaaloha o nā mea kūkākūkā mai nā wahi a puni o ka honua.

Ma luna aʻe nā mea lako hale hana maʻamau, me ka piʻi ʻana o ka ʻike o ka poʻe i ka pale ʻana iā lākou iho, ua hoʻololi mālie ʻia nā lako aniani brittle e nā mea plastik, a lilo i mea maʻamau i hoʻohana ʻia i nā mea hoʻopau.
