Kab lus no muab cov kev tshawb nrhiav kom meej meej txog vim li cas polypropylene feem ntau siv hauv cov rooj tog zaum (chaw tshawb fawb dav dav. Nws nthuav dav ntawm cov ntsiab lus tseem ceeb thiab suav nrog cov ncauj lus sib piv, cov ntawv thov, thiab txhawb cov ntaub ntawv kom nkag siab rau cov kws tshaj lij thiab nyiam ib yam nkaus.
Txheej txheem cej luam ntawm polypropylene
Polypropylene (PP), ib thermoplicity polymer, yog ib feem ntawm cov polyolefin pab pawg thiab paub txog nws cov versatility. Thawj polymerized nyob rau xyoo 1951, nws yog qhov thib ob-feem ntau dav cov khoom lag luam yas tom qab polyethylene. Nws cov khoom muaj xws li cov tshuaj lom neeg muaj zog, tshuab zog, thiab kub ua zog, ua rau nws haum rau ntau yam kev siv, suav nrogRooj tog cev.
Cov Khoom Siv Tseem Ceeb Txhawb Nqa Chav (lab
Tshuaj Kuj
Cov ntaub pua uas feem ntau cuam tshuam nrog cov tshuaj hnyav, thiab polypropylene tsis kam rau acids, hauv paus, thiab cov kuab tshuaj ua rau nws zoo tagnrho. Nws tsis tawg yooj yim, ua kom cov rooj tog zaum ntev nyob ntev hauv cov chaw hauv corrosive, xws li trace hlau tsom xam lossis ntsuas toxicology.
Durability thiab tawv
Polypropylene yog qhov ruaj khov thiab tiv taus kev tawg lossis tawg, uas yog qhov tseem ceeb rau kev txhawb nqa cov cuab yeej siv hnyav thiab nrog kev siv txhua hnub muaj zog. Nws lub siab melting point (327 degree f lossis 163.8 degree) ntxiv rau nws lub sijhawm ntev.
Yooj yim los ntxuav thiab tswj hwm
Nrog rau txoj kev du nto, polypropylene yog yooj yim los ntxuav, uas yog qhov tseem ceeb rau kev tswj kom muaj zog thiab tiv thaiv kev paug hauv cov labs. Qhov no ua rau nws haum rau kev tsis muaj menyuam thiab phais.
Lub teeb yuag thiab raug nqi
Ua lub teeb yuag, polypropylene rooj tog zaum tau yooj yim txav thiab rov ua haujlwm, txhim kho kev kuaj ua ntsuas. Nws tseem muaj ntau tus nqi pheej yig rau cov ntaub ntawv xws li cov hlau stainless, ua rau nws xaiv ua cov khoom siv ntau.
Tsis yog-corrosive thiab ib puag ncig tus phooj ywg
Tsis zoo li cov hlau, polypropylene tsis xeb lossis corrode, uas tau txais txiaj ntsig hauv cov chaw noo nyob. Nws tseem rov ua dua tshiab, ua cov khoom pov tseg tsis tshua muaj, ntxiv rau nws qhov kev thov ib puag ncig.
Kev sib piv nrog lwm cov ntaub pua rooj tog zaum
Txhawm rau kom nkag siab polypropylene txoj kev zoo, nws muaj txiaj ntsig zoo los sib piv nws nrog cov kev xaiv ib leeg:
| Khoom | Tshuaj Kuj | Yam ruaj khov | Tus nqi | Qho hnyav | Kho |
|---|---|---|---|---|---|
| Polypropylene (pp) | Siab (tshwj tsis yog oxidizing acids) | Siab | Tsawg-nruab nrab | Lub teeb yuag | Yooj yim los ntxuav |
| Stainless hlau | Siab | Siab heev | Siab | Hnyav | Tswj kav |
| Ntoo (nrog ua tiav) | Kev Ntsuas Hluav Taws Xob (Tshuaj-Cov Tshuaj Tiv Thaiv Kom Ua tiav) | Siab | Nruab nrab | Hnyav | Yuav tsum tau saib xyuas |
| Epoxy Resin | Siab | Siab | Nruab nrab-siab | Hnyav | Yooj yim los ntxuav |
| Yas Laminate | Tsawg-nruab nrab | Tswj kav | Qi | Lub teeb yuag | Yooj yim los ntxuav |
Polypropylene tau dav hauv cov rooj tog zaum uas feem ntau rau cov chaw ua haujlwm zoo li kev nyab xeeb hauv kev ua haujlwm zoo li trace hlau kev tsom xam lossis ntsuas toxicology. Txawm li cas los xij, nws tshaj plaws tseem ceeb tshaj plaws yog nws cov nplaim taws, raws li nws tuaj yeem hlawv cov khoom siv hluav taws xob sai thiab tso cov tshuaj lom neeg lossis kev saib xyuas kev nyab xeeb kev nyab xeeb.
Cov ntawv thov hauv chaw kuaj rooj tog
- Lub tub rog: Suav nrogTshuaj Cia Khoom, Acid Cabinets, Thiab Flammable / Cov Khoom Siv CiaCov. Cov no yog tsim rau ntau yam xav tau kev cia siab, ua kom tsis muaj hlau kom tiv thaiv corrosion.
- Ua haujlwm thiab rooj: Lub teeb ci ntsa iab thiab ruaj khov thiab ruaj khov, haum rau cov kev ua si txhua hnub, suav nrog cov hauv paus thiab cov chav nyob txawb rau kev txhim kho kom zoo.
- Lub luag haujlwm: Encompasses rooj zaum thiab chaw ua haujlwm thaj chaw, tseem ceeb rau kev sim hauv cov kev ua kom haum.
- Fums hoods: Qhov tseem ceeb rau kev tiv thaiv cov pa taws ua xeb, nrog polypropylene kev tsim kho zoo tshaj rau kev sib tw acids thiab cov hauv paus, tshwj xeeb hauv kev txiav cov kab hlau.
- Lub hauv paus bootes: Corrosion-resistant, haum rau cov chaw ua haujlwm ntub dej, uas tsis muaj hlau thiab muab ntau yam dab dej ntau thiab tsawg.
- Tshwj Xeeb Cia: Suav nrog cov kua qaub thiab cov twj tso kua mis, kom muaj kev nyab xeeb hauv cov chaw hnyav nrog cov tshuaj muaj hnyav.
- Hauv caug chaw Panels thiab Fillers: Muab kev hloov pauv tau, xws li lub hauv caug qhib thiab khib nyiab ntim thaj chaw, txhim kho kev ua haujlwm lab.
