Ib tug tsis tuaj yeem kwv yees qhov tseem ceeb ntawm lub luag haujlwm ntawm cov khoom siv xws li iav hauv kev tsim kho niaj hnub no. Cov khoom no maj mam pib hloov cov phab ntsa, thiab suav hais tias yog ib qho cim ntawm kev siv cov cuab yeej siv siab thaum tsim kho. Hauv kab lus no, peb yuav saib seb lub iav polymer yog dab tsi, nws siv li cas hauv kev tsim kho, nrog rau nws cov yam ntxwv.

siv kev tsim kho

Cov tsev niaj hnub, feem ntau hauv cov nroog loj, hauv lawv cov qauv muaj ntau yam sib txawv uas yog ua los ntawm iav. Cov khoom no rau lub sijhawm ntev tsis suav tias yog qhov loj heev, nrog rau malleable rau qhov kev ntxhov siab me ntsis. Qhov no yav tas los muaj nyob analogues uas vau nrog tsim ntawm ntau me me fragments los ntawm tej lub siab los yog tej yam. Tam sim no muaj ntau yam niaj hnub uas muaj zog dua. Piv txwv li, polymer iav. Nws tshwm sim hauv khw nyuam qhuav tsis ntev los no.

Kev piav qhia dav dav

Cov khoom no tuaj yeem hu ua kev txhim kho tshiab kawg. Rau kev tsim cov iav polymer, cov khoom siv polymer yog siv uas muaj cov khoom sib txawv ntawm qhov pom tseeb raws li qhov qub. Tsis tas li ntawd, nws muaj cov txheej txheem tshwj xeeb ntawm qhov txawv txav uas tso cai rau nws kom ua tau zoo tshaj qhov yooj yim quartz counterpart.

Ua ntej tshaj plaws, cov khoom no muaj zog ntau dua li qhov yooj yim. Cov khoom raws li nws yuav nyuaj heev rau kev tawg. Tsis tas li ntawd, cov tsom iav zoo li no tsis raug tsim los ntawm khawb thiab splinters thaum lub sijhawm ua haujlwm ntev. Acrylic kuj tseem siv rau hauv kev tsim khoom, uas tso cai rau kev tsim cov khoom ntawm qhov xav tau kev teeb tsa los ntawm hom iav no.

Vim cov txiaj ntsig no, cov khoom siv yog siv rau kev tsim ntau yam pob tshab, qab nthab hauv tsev lossis lo ntsiab muag. Polymer iav feem ntau yog siv rau iav.

khoom siv ua kua

Cov khoom no kuj tseem hu ua silicate nplaum. Liquid polymer iav feem ntau yog siv thaum lub sij hawm tsim kho ntawm ntau yam qauv thiab niaj hnub vaj tse. Nws yog tsuas yog pom nyob rau hauv muaj pes tsawg leeg ntawm cov pob zeb sib tov, uas yog siv ob qho tib si rau sab hauv thiab sab nrauv kho kom zoo nkauj ntawm lub tsev nyob rau hauv thiaj li yuav impart thiab txhim kho waterproofing thiab refractory zog. Raws li rau cov tshuaj muaj pes tsawg leeg, kua iav yog hydro-solution ntawm poov tshuaj los yog sodium silicate. Cov khoom no yog tsim nyob rau hauv ob txoj kev:

1. Melting sand as well as sodium carbonate.
2. ImpactCov tshuaj uas muaj sodium thiab potassium silicates ntawm silica.

Ntxiv cov khoom siv no rau cov pob zeb yuav ua kom cov khoom zoo, nrog rau kev ua kom lub neej ua haujlwm ntawm lub tsev ntau zaus dhau.

Daim ntawv thov ntawm cov ntawv polymer

Feem ntau, cov khoom siv no yog siv thaum lub sij hawm tsim cov pas dej da dej, da dej galvanic, hauv kev tsim cov thawv, cua qhov hluav taws xob thiab ntau ntxiv. Cov iav nrog cov yeeb yaj kiab polymer, GOST 32563-2013, feem ntau yog siv rau cov pas dej da dej, vim tias cov khoom siv no yeej ntseeg tau thiab zoo. Kev tsim khoom tau tsim tau ntau xyoo. Tam sim no, technologists tsim cov khoom siv raw ntawm ntau qhov ntom ntom. Nws yog nyob ntawm seb qhov tuab, nrog rau qhov hnyav ntawm cov iav polymer, hloov pauv. Nws yuav tsis ntev los kho koj lub pas dej ua ke nrog cov khoom no, ntseeg kuv.

txiaj ntsig

Ua ntej yuav cov nplooj ntawv piav qhia, koj yuav tsum tau them sai sai rau cov yam ntxwv tseem ceeb ntawm cov khoom siv no. Nyob rau hauv txhua rooj plaub, polymer iav muaj ntau yam zoo dua. Thaum piv nrog lwm cov ntaub ntawv zoo sib xws. Ua ntej ntawm tag nrho cov, zoo heev ductility thiab tsim kua muag zog yuav tsum tau highlighted. Kev ntseeg tau ntawm cov khoom siv no yog nyob rau hauv qhov tseeb hais tias nyob rau hauv cov ntaub ntawv ntawm ib tug muaj zog shock load, tawg tsis tsim rau nws. Hauv lwm lo lus, tsom iav polymer yuav ua haujlwm ntev ntev ntawm huab cua kub. Nws tseem tsim nyog hais txog cov tshuaj tiv thaiv. Txawm tias ultraviolet yuav tsis txaus ntshai rau cov khoom no. Tsuas yogNtxiv mus, nws tsis ntshai ntawm thermal oxidation. Thaum lub sij hawm yuav khoom, kuj xyuam xim rau lub load thiab nta ntawm lub iav nto. Qhov tuab ntawm cov khoom, nrog rau nws cov nqi, yuav nyob ntawm qhov no.

Yuav khoom

Tus nqi ntawm cov iav polymer tam sim no yog qhov tsim nyog thiab tsim nyog. Tau siv cov khoom siv no hauv kev tsim kho ib zaug, koj yuav xav yuav nws dua. Txhawm rau txhim kho cov khoom siv kho tshuab thiab lub cev ntawm cov khoom siv, ntau cov thev naus laus zis siv rau ntau yam khoom siv ntxiv. Txhawm rau ntxiv dag zog rau lub khob, tam sim no tau npog nrog zaj duab xis uas tiv thaiv qhov chaw ntawm khawb, nrog rau scuffs uas yuav tshwm sim thaum lub sijhawm thauj mus los.

Kom tsis txhob muaj teeb meem thaum lub sijhawm thauj mus los, kev saib xyuas tshwj xeeb yuav tsum tau them rau hom iav, nrog rau kev muaj daim ntawv pov thawj rau nws. Yog tias tsim nyog, koj tuaj yeem siv kev pab ntawm hydraulic engineers uas yuav xam kom meej thiab muab cov lus pom zoo ntawm kev xaiv cov khoom siv. Tau kawg, rau kev txiav thiab vuam cov khoom hauv kev kawm, nws yog qhov zoo dua los siv cov kev pabcuam ntawm cov kws tshaj lij uas muaj txhua yam tsim nyog rau lub hom phiaj no.

Nws yuav tsum tau hais dua tias cov iav polymer txawv ntawm lwm cov ntaub ntawv hauv lawv qhov muaj thiab tus nqi qis. Rau ntau tus neeg, nws yog qhov txheej txheem kawg uas txiav txim siab.

Small xaus

Txhawm rau sau tag nrho cov saum toj no, nws tsim nyog sau cia tias cov iav polymer nyob hauvtam sim no ib qho khoom siv zoo heev nrog lub zog siab thiab kev ntseeg siab rau kev tsim kho ntawm ntau yam qauv thiab cov tsev. Ntau lub khw muag khoom xaiv cov khoom siv no rau kev tsim cov showcases. Ntau tus sib cav hais tias nws yog qhov zoo dua los muab nyiaj rau cov khoom siv zoo ib zaug dua li yuav "pheej yig" ib zaug ob peb zaug, uas tawg thiab tawg ntawm qhov me me los yog cuam tshuam. Feem ntau, kev tshuaj xyuas ntawm cov khoom siv feem ntau yog qhov zoo. Tej zaum koj yuav tsum xav txog kev tsim nws thiab?
