Cov neeg uas nyiam kev tsim kho niaj hnub lossis kev tsim khoom feem ntau tuaj hla cov khoom xws li polyurethane. Nws yog dab tsi thiab nws siv li cas, koj tuaj yeem kawm paub meej hauv kab lus no. Cov tshuaj no yog ib tug heev elastic polymer, uas yog dav siv nyob rau hauv ntau yam ntawm peb lub neej: kev tsim kho, tshuaj, hnyav, khau los yog khaub ncaws industries. Lawm, cov khoom no yog hluavtaws. Nws muaj ntau yam txiaj ntsig, uas tam sim no koj yuav kawm txog.

Khoom muaj nqis

Cov khoom nthuav tawm muaj ntau qhov zoo:

· Resistant hnav, laus thiab lwm yam cuam tshuam.

Siab zog.

· Nws tuaj yeem hloov qib ntawm elasticity ntawm cov khoom.

· Muaj peev xwm siv cov khoom nyob rau hauv siab load.

Dav kub ntau yam uas polyurethane (qhov koj twb paub lawm) tuaj yeem siv tau.

Siv tau rau ntau thaj chaw ntawm tib neeg lub neej.

Sealants, khaub ncaws, rwb thaiv tsev, khau, kav dej thiab lwm yam khoom siv hauv lub neej txhua hnub yog tsim los ntawm nws.

Durability.

Muajnqe. Cov khoom no, txawm tias nws muaj tus yam ntxwv zoo li cas, yog pheej yig, yog li txhua tus uas muaj qhov nruab nrab thiab txawm tias cov nyiaj hli tsawg kawg tuaj yeem yuav nws.

Kev ua tau zoo thiab siv tau ntau yam.

Tsis muaj deformation.

· Tsis txhob tso cov cim rau ntawm qhov chaw uas lawv cuam tshuam.

Khoom thiab specifications

Cov khoom siv niaj hnub no feem ntau yog polyurethane. Nws yog dab tsi, dab tsi zoo nws muaj, koj twb paub lawm. Tam sim no cia peb tham txog cov yam ntxwv ntawm cov khoom no.

Yog li, cov khoom siv nthuav tawm tuaj yeem ua haujlwm nyab xeeb hauv qhov chaw nruj, thaum nws cov khoom siv tau zoo tsis hloov pauv. Tsis tas li ntawd, cov khoom siv zoo kawg nkaus siv nyob rau hauv qhov kub thiab txias: los ntawm -60 txog +80 degrees. Qee lub sij hawm nws tuaj yeem ua kom sov rau 120 o, tab sis cov txheej txheem no yuav tsum tsis txhob siv sijhawm ntev, txwv tsis pub cov khoom yuav tsuas vau.

Cov polymer muaj peev xwm tiv taus cov khoom hnyav, tsis tshua muaj kev laus dua lwm yam. Nws yog resistant rau hnav, noo noo, kub heev, tshav ntuj, ntsev, organic solvents. Polyurethane (nws yog dab tsi, koj twb paub lawm) suav hais tias yog cov khoom siv ruaj khov heev. Nyob rau tib lub sijhawm, nws cov elasticity tuaj yeem raug programmed thaum lub sijhawm tsim khoom. Cov khoom siv no yuav muaj cov yam ntxwv sib txawv, nyob ntawm qhov uas nws daim ntawv thov nyob ntawm. Nws yuav tsum tau muab sau tseg tias polyurethane tej zaum yuav muaj ib los yog ntau yam Cheebtsam.

Ntau lawm ntasubmissions

Nws yuav tsum raug sau tseg tias kev tsim cov polyurethane tsis yooj yim. Nws yuav siv sij hawm ntau ntawm kev siv zog, kev ua haujlwm thiab lub zog. Cov txheej txheem nws tus kheej siv qhov chaw los ntawm kev sib xyaw thiab kev kho cua sov ntawm ob peb lub ntsiab lus: polyol thiab isocyanate. Tsis tas li ntawd, polyesteramines kuj ntxiv rau qhov sib tov. Tag nrho cov txheej txheem yog ua los ntawm cov khoom kim heev.

Nws yuav tsum raug sau tseg tias cov khoom siv raw yog tsim nyob rau hauv ob peb lub tebchaws: Russia, Lub Tebchaws Yelemees, Tebchaws Asmeskas thiab Ltalis. Cov ntaub ntawv nthuav tawm yog tsim thiab ua tiav ntau txoj hauv kev: casting, nias, extrusion.

Cov khoom twg yog tsim los ntawm cov khoom no?

Polyurethane yog cov khoom siv ntau heev. Ntau yam khoom yog tsim los ntawm nws. Piv txwv li, nyob rau hauv cov tshuaj, nws yog siv los tsim cov hnab looj tes, uas yog ruaj, du, tsis muaj nqi, thiab ib puag ncig tus phooj ywg. Cov log tsheb rau tsheb log kuj yog tsim los ntawm cov khoom nthuav tawm. Tsis tsuas yog lawv kav ntev dua cov roj hmab, tab sis lawv kuj tsis muaj qhov cim tseg.

Nws tseem yuav tsum nco ntsoov tias cov khoom siv polyurethane xws li o-rings, bushings, cuffs. Cov tshuaj no yog siv los ua cua sov. Cov ntaub ntawv nthuav tawm kuj tseem siv hauv kev lag luam rooj tog rau kev tsim cov txaj. Yog tias koj yuav polyurethane rollers, ces koj tuaj yeem paub tseeb tias lawv yuav kav ntev.

Los ntawm cov khoom no kuj tsimntau yam ntawm lub khob nqus dej, cov lus qhia, cov ntaub qhwv, cov ntaub hauv ob sab phlu, pulleys, yeeb nkab thiab lwm yam khoom.

Cov kua polyurethane siv nyob qhov twg?

Kuv yuav tsum hais tias cov khoom siv no tuaj yeem siv ntau hom: kua, foamed thiab khoom. Thawj hom khoom siv feem ntau yog siv los tiv thaiv lub ru tsev tiaj tus. Qhov zoo ntawm cov khoom siv no yog tiv taus hnav, ya raws thiab lwm yam cuam tshuam sab nraud. Tsis tas li ntawd, cov kua polyurethane tuaj yeem siv rau thaj chaw nyuaj ntawm lub ru tsev, qhov twg nws yuav nyuaj rau siv lwm cov insulator.

Nws yuav tsum tau muab sau tseg tias cov khoom uas tau nthuav tawm tuaj yeem siv los kaw qhov thiab cov kab nrib pleb hauv lub ru tsev qub. Qhov zoo ntawm xws li waterproofing yog:

- adhesion zoo;

- kom qhuav sai;

- zog;

- muaj;

- yooj yim siv;

- tiv thaiv qhov tsis zoo ntawm ib puag ncig sab nraud;

- ecological huv huv.

Cov khoom siv kho kom zoo nkauj los ntawm cov khoom siv nthuav tawm: qhov zoo thiab cov yam ntxwv ntawm kev siv

Nws yuav tsum tau hais tias cov khoom siv nthuav tawm yog siv los tsim cov khoom kho kom zoo nkauj sab hauv. Piv txwv li, zoo nkauj polyurethane yog siv rau zus tau tej cov cornices, qab nthab moldings los yog lwm yam khoom. Nrov heev yog stucco molding los ntawm cov khoom nthuav tawm. Nws yog qhov txawv los ntawm nws lub zog, tsis kam mus rau cov neeg kho tshuab kev ntxhov siab, muaj peev xwm tsim cov duab tsis zoo. Nws yuav tsum raug sau tseg tias koj tuaj yeem ua cov khoom dai rau ntawmorder.

Qhov zoo ntawm cov khoom no yog:

- zog;

- hniav ntxim nyiam;

- yooj yim ntawm kev teeb tsa;

- yooj yim ntawm kev saib xyuas thiab ua haujlwm;

- tus nqi qis;

- sib txawv ntxoov.

Nws yuav tsum tau hais tias, tsis zoo li plaster hniav ntsiab, cov khoom polyurethane tsis tig daj dhau sijhawm. Ntxiv nrog rau cornices, koj tuaj yeem xaj cov khoom ntawm txhua kab, pilasters, kab teeb rau stairs.

Nta thiab siv ntawm polyurethane ua npuas ncauj

Cov khoom siv nrov tshaj plaws hauv kev tsim kho thiab kho yog polyurethane ua npuas ncauj. Nws muaj qhov hnyav qis, zoo cua sov thiab suab rwb thaiv tsev zoo, nrog rau cov nqi qis. Nws yog resistant rau chav, noo noo, tshav ntuj thiab kub heev.

Siv cov khoom no yooj yim heev. Koj tsuas yog yuav tsum tau siv nws mus rau qhov chaw xav tau. Txawm li cas los xij, ib qho yuav tsum tau coj mus rau hauv tus account qhov tseeb tias cov khoom muaj peev xwm nce qhov loj. Qhov zoo ntawm cov khoom yog adhesion zoo, muaj peev xwm staining.

Hauv paus ntsiab lus, cov no yog tag nrho cov yam ntxwv ntawm kev siv cov khoom nthuav tawm. Hmoov zoo!
