xov xwm

Cov khoom ntim yog hais txog cov ntaub ntawv siv los ua ntau lub ntim ntim thiab ua tau raws li cov kev xav tau ntawm cov khoom ntim, uas yog cov khoom siv hauv cov khoom ntim khoom.Nws yog ib qho ntawm cov xwm txheej tseem ceeb rau kev tsim cov ntim kom nkag siab thiab paub cov hom, cov khoom thiab siv cov khoom ntim thiab xaiv cov khoom ntim kom tsim nyog.

Kev xaiv cov qauv ntawm cov khoom ntim

Kev xaiv cov ntaub ntawv tseem ceeb heev hauv kev ntim khoom.Yog tias cov khoom siv tsis tsim nyog, nws yuav ua rau qhov tsis tsim nyog poob rau lub lag luam.Kev xaiv cov khoom ntim yuav tsum tau txiav txim siab raws li cov yam ntxwv ntawm cov khoom lawv tus kheej, thiab cov hauv paus ntsiab lus ntawm kev tshawb fawb, kev lag luam thiab kev tiv thaiv ib puag ncig.

1.Raws li cov khoom xav tau

Kev xaiv cov ntaub ntawv tsis yog arbitrary.Ua ntej tshaj plaws, cov khoom siv yuav tsum raug xaiv raws li cov yam ntxwv ntawm cov khoom lag luam, xws li daim ntawv ntawm cov khoom (khoom, kua, thiab lwm yam), seb nws puas yog corrosive thiab volatile, thiab seb nws puas yuav tsum tau khaws cia deb ntawm lub teeb. .Qhov thib ob, peb yuav tsum xav txog qib ntawm cov khoom.Cov khoom ntim ntawm cov khoom lag luam qib siab lossis cov cuab yeej precision yuav tsum tau ua tib zoo saib xyuas lawv qhov zoo nkauj thiab ua haujlwm zoo;Cov khoom ntim ntawm cov khoom lag luam nruab nrab yuav tsum tau them nyiaj sib npaug rau kev zoo nkauj thiab kev ua tau zoo;thaum cov khoom ntim khoom ntawm cov khoom qis qis yuav tsum muab qhov tseem ceeb rau kev ua tau zoo.

2.Kev tiv thaiv ntawm cov khoom

Cov ntaub ntawv ntim khoom yuav tsum tiv thaiv cov khoom lag luam zoo, yog li nws yuav tsum muaj qee lub zog, toughness thiab elasticity, hloov mus rau qhov cuam tshuam ntawm lub siab, cuam tshuam, kev co thiab lwm yam sab nraud.

3.Economical thiab ib puag ncig tus phooj ywg

Cov khoom ntim yuav tsum raug xaiv kom deb li deb tau los ntawm ntau qhov chaw, yooj yim, tus nqi qis, rov ua dua, degradable, ua cov khoom tsis muaj kuab paug, thiaj li tsis ua rau muaj kev phom sij rau pej xeem.

Cov khoom ntim khoom siv dav dav thiab lawv cov yam ntxwv ua haujlwm

Muaj ntau yam khoom ntim khoom.Feem ntau siv tam sim no yog ntawv, yas, hlau, iav, ceramics, cov ntaub ntawv ntuj, cov khoom siv fiber ntau, cov ntaub ntawv sib xyaw thiab cov khoom siv tiv thaiv ib puag ncig tshiab degradable.

1.Cov ntaub ntawv ntim khoom

Nyob rau hauv tag nrho cov txheej txheem ntawm kev tsim khoom ntim, cov ntawv ntim khoom, raws li cov khoom ntim khoom siv, tau siv dav hauv kev tsim khoom thiab kev ua neej nyob, los ntawm cov khoom lag luam, ntim hluav taws xob, mus rau cov hnab ntim khoom plig, los ntawm cov ntawv ntim khoom rau cov ntawv ntim khoom sib xyaw. , txhua yam qhia txog kev ntxim nyiam ntawm cov ntawv ntim khoom.

Cov ntaub ntawv ua tiav yog qhov yooj yim, tus nqi qis, tsim nyog rau kev tsim khoom loj thiab kev luam ntawv zoo, thiab muaj qhov zoo ntawm kev rov ua dua tshiab, kev lag luam thiab kev tiv thaiv ib puag ncig.

2. cov khoom ntim yas

Yas yog ib hom khoom siv hluavtaws hluavtaws polymer.Nws yog ib qho yooj yim los tsim, thiab muaj cov khoom zoo ntawm dej tsis kam, noo noo tsis kam, roj tsis kam thiab rwb thaiv tsev.Nrog ntau cov khoom siv raw, tus nqi qis thiab kev ua haujlwm zoo, nws tau dhau los ua cov khoom ntim ceev tshaj plaws hauv ntiaj teb hauv 40 xyoo dhau los thiab yog ib qho tseem ceeb tshaj plaws ntawm cov khoom ntim khoom ntim khoom niaj hnub no.

3.Cov khoom siv hlau ntim

Raws li ib qho ntawm cov khoom ntim khoom, hlau yog dav siv hauv kev lag luam ntim khoom, ntim khoom thauj thiab muag ntim, thiab ua lub luag haujlwm tseem ceeb hauv cov khoom ntim.

4.Glass, ceramic ntim khoom

1) iav

Cov ntaub ntawv yooj yim ntawm iav yog quartz xuab zeb, caustic soda thiab limestone.Nws muaj cov yam ntxwv ntawm siab transparency, impermeability thiab corrosion kuj, non-toxic thiab tasteless, ruaj khov tshuaj ua tau zoo thiab tsis tshua muaj nqi ntau lawm thiab yuav ua tau rau hauv pob tshab thiab translucent ntim ntawm ntau yam duab thiab xim.

iav yog dav siv nyob rau hauv ntim cov roj, cawv, zaub mov, dej haus, jam, tshuaj pleev ib ce, condiments thiab kws tshuaj.

2) ceramic

Ceramics muaj kev ruaj ntseg zoo thiab thermal stability, thiab tuaj yeem tiv taus kub thiab corrosion ntawm ntau yam tshuaj.Kev hloov pauv sai hauv tshav kub thiab txias tsis cuam tshuam rau ceramics, tsis muaj deformation thiab deterioration rau xyoo.Nws yog cov khoom ntim zoo tagnrho rau cov khoom noj thiab tshuaj.Ntau lub ntim ntim ceramic nws tus kheej yog cov khoom siv tes ua zoo, thiab muaj qhov tshwj xeeb daim ntawv thov tus nqi hauv kev ntim khoom.

5.Natural ntim khoom

Cov khoom ntim ntuj xa mus rau tsiaj tawv nqaij, plaub hau lossis nplooj nplooj, stems, rods, fibers, thiab lwm yam, uas tuaj yeem siv los ua cov khoom ntim ncaj qha lossis tsuas yog ua tiav rau hauv daim hlau lossis cov ntawv.

6.Fiber ntaub ntim khoom

Cov ntaub fibers yog mos, yooj yim rau luam tawm thiab zas xim, thiab tuaj yeem siv thiab rov ua dua tshiab.Tab sis nws cov nqi yog siab dua, ruaj khov yog tsawg, feem ntau siv rau lub ntim ntim ntawm cov khoom, xws li filling, kho kom zoo nkauj, shockproof thiab lwm yam haujlwm.Fiber ntaub ntim cov ntaub ntawv nyob rau hauv kev ua lag luam tuaj yeem muab faib ua ntuj fiber ntau, txiv neej ua fiber ntau thiab hluavtaws fiber ntau.

7.Cov khoom ntim khoom sib xyaw

Cov khoom sib xyaw ua ke yog ua los ntawm ob lossis ntau hom khoom siv los ntawm qee txoj kev thiab kev txhais tau tias kom nws muaj cov yam ntxwv ntawm ntau yam khoom siv los ua kom tsis muaj qhov tsis zoo ntawm ib qho khoom siv, tsim cov khoom ntim zoo tshaj plaws nrog cov khoom zoo.Piv nrog rau cov khoom siv ib txwm siv, cov ntaub ntawv sib xyaw muaj qhov zoo ntawm kev txuag cov peev txheej, yooj yim rov siv dua, txo cov nqi tsim khoom thiab txo cov ntim ntim, yog li nws muaj txiaj ntsig ntau dua thiab tawm tswv yim.

8.New ib puag ncig-phooj ywg degradable ntim cov ntaub ntawv

Cov ntaub ntawv tshiab hauv ib puag ncig yog cov khoom sib xyaw tsim los txo cov pa phem dawb, uas feem ntau yog ua los ntawm kev sib xyaw ntoo lossis lwm yam nroj tsuag.Nws yog biodegradable thiab tsis yooj yim ua rau muaj kuab paug, thiab yog lub ntsiab kev loj hlob ntawm cov khoom ntim rau yav tom ntej.
