Polyurethane chaw tsim khoom nyob rau plaub txheej txheem loj: Cast Polyurethane Elastomer (CPU) ua, Thermoplastic Polyurethane Elastomer (TPU) ua, Polyurethane Ua Npuas Ncauj (rigid / saj zawg zog) ua, thiab Polyurethane Txheej txheej. Thaum tag nrho plaub poob rau hauv tsev neeg cov ntaub ntawv polyurethane dav, lawv sib txawv hauv cov qauv kev sib txuas, cov txheej txheem ua, thiab xaus - siv daim ntawv thov, ua ke tsim cov txheej txheem tseem ceeb ntawm kev lag luam polyurethane. Cov ntsiab lus yog raws li nram no:
Casting Polyurethane Elastomer (CPU) ua
Cov yam ntxwv ntawm cov txheej txheem: Siv cov huab cua- siab, qhib- nchuav casting yam tsis tas yuav tsum muaj siab - cov cuab yeej siv siab, muab kev ua haujlwm siab. Txij li thaum cov khoom siv raw yog nyob rau hauv cov kua ua ntej casting, nws tuaj yeem ua tiav cov pwm kab noj hniav, uas txhais tau hais tias cov cuab yeej precision yuav tsum tau ua kom yooj yim dua - tso cai rau cov lag luam me thiab nruab nrab - cov lag luam loj kom ua tiav cov khoom lag luam nrog cov cuab yeej siv qis qis.
Kev ua tau zoo ntawm cov khoom: Muaj ntau yam hardness (50A-85D), hloov tau rau ntau hom kev xav tau; pwm tsim yog yooj yim, haum rau ntau yam ntau lawm, thiab tsis txwv los ntawm cov khoom loj. CPU cov ntaub ntawv kuj tseem muaj qhov ua tau zoo heev, kev tiv thaiv roj, thiab lub zog tsim kua muag, uas yog qhov tseem ceeb kom zoo dua qhov txawv ntawm cov khoom siv roj hmab zoo tib yam.
Daim ntawv thov scenarios: Tsim nyog rau kev tsim cov khoom siv elastomer uas xav tau kev hloov kho, qhov loj me, lossis cov duab nyuaj, xws li kev lag luam poob siab absorbers thiab cov ntsaws ruaj ruaj. Nws kuj yog siv dav hauv hnyav-lub luag haujlwm, hnav- cov ntawv siv tiv thaiv nrog rau cov ntxaij vab tshaus mining, luam ntawv rollers, thiab couplings.
Thermoplastic Polyurethane Elastomer (TPU) Ua
Cov yam ntxwv txheej txheem: Siv PU pellets ua raw khoom, uas yog yaj ntawm qhov kub thiab txias thiab txhaj tshuaj - molded - cov txheej txheem thermoplastic. Txoj kev no ua rau kev ua haujlwm tas mus li, tsis siv neeg ntau lawm thiab sib koom ua ke nrog cov khoom siv xws li kev txhaj tshuaj molding thiab extrusion tshuab, ua kom luv luv ntau lawm.
Cov khoom ua tau zoo: Kev ua haujlwm siab ntau lawm thiab tus nqi qis; ceev curing ceev, tab sis nrog loj deformation, ua rau nws haum rau me me - cov khoom loj; kev sib raug zoo ntawm kev sib piv yog qhov tsis muaj zog, txwv nws siv hauv siab -load daim ntawv thov. Txawm li cas los xij, TPU muaj cov khoom siv rov ua dua tshiab thiab rov ua dua tshiab, ua raws li cov qauv tam sim no mus rau ib puag ncig kev ruaj ntseg thiab kev lag luam ncig.
Daim ntawv thov scenarios: Tsim nyog rau cov khoom me me hauv qis - nrawm, qis- daim ntawv thov thauj khoom, xws li cov ntaub ntawv khau, rooj plaub hauv xov tooj, thiab cov khoom siv niaj hnub. Nyob rau hauv xyoo tas los no, kev thov kuj tau loj hlob tsis tu ncua hauv thaj chaw xws li hluav taws xob cable sheathing thiab cov khoom ntaus pob ncaws pob.
Polyurethane Ua Npuas Ncauj (Ntxig / Flexible) ua
Cov yam ntxwv txheej txheem: Cov txheej txheem ua npuas dej yog tsim los ntawm cov txheej txheem foaming, muab faib ua pawg ua npuas ncauj nruj thiab yoog raws. Los ntawm kev kho tus neeg sawv cev sib piv thiab cov tshuaj tiv thaiv kub thaum lub sij hawm foaming, cell density thiab pore loj tis tuaj yeem tswj tau, ua kom muaj kev hloov kho kev ua haujlwm.
Product Performance:
Rigid ua npuas ncauj: High ceev, siab zog, thiab zoo heev thermal rwb thaiv tsev kev ua tau zoo, nrog tsawg thermal conductivity- lees paub tias yog ib qho ntawm cov khoom siv tau zoo tshaj plaws -txuag cov ntaub ntawv hauv lub tsev thiab txias - chains insulation sectors.
Flexible foam: Tsawg ntom, siab softness, thiab zoo resilience, nrog rau zoo breathability thiab kev nplij siab.
Daim ntawv thov scenarios:
Rigid ua npuas ncauj: Feem ntau yog siv rau cov khoom siv rwb thaiv tsev txheej (xws li cov tub yees) thiab cov ntaub ntawv thaiv phab ntsa, thiab kuj tau siv dav hauv kev cia txias thiab cov yeeb nkab rwb thaiv tsev rau kev txuag hluav taws xob.
Ua npuas ncauj yooj yim: Siv dav hauv cov ntaub ntawv upholstery (xws li rooj tog padding) thiab cov khoom siv sab hauv tsheb (xws li cov rooj zaum), thiab tseem tuav ib qho chaw tseem ceeb hauv cov khoom hauv tsev xws li txaj thiab sofas.
Polyurethane Txheej Txheej
Cov yam ntxwv txheej txheem: Siv polyurethane resin ua cov khoom siv hauv paus, siv los ntawm kev txau lossis txhuam los ua txheej txheej. Once cured, it forms a dense, continuous protective film with strong adhesion, and coating thickness and gloss level can be adjusted according to requirements.
Product Performance:
Engineering los tiv thaiv -corrosion: Muaj zog tiv thaiv cov tshuaj tiv thaiv corrosion thiab puas, haum rau hnyav kev lag luam ib puag ncig, nrog rau huab cua tiv thaiv zoo uas tswj kev ua haujlwm ruaj khov nyob rau lub sijhawm ntev txawm tias nyob rau sab nraum zoov hnyav.
Kho kom zoo nkauj: nplua nuj xim thiab siab gloss, txhim kho cov khoom zoo nkauj thiab kev ntxhib los mos; cov txheej kuj muaj cov℃ntawm yellowing kuj, cov xim ntxiv - ruaj khov tshaj kev siv txuas ntxiv.
Daim ntawv thov scenarios:
Engineering tiv thaiv-corrosion: Siv rau cov qauv hlau, cov kav dej, thiab lwm yam kev siv uas xav tau kev tiv thaiv ntev -, nrog rau kev siv dav hauv choj, nkoj, thiab cov khoom siv petrochemical ib yam nkaus.
Kho kom zoo nkauj coatings: Siv nyob rau hauv nto tiav rau tsheb, rooj tog, thiab kev tsim kho, thiab kuj tseem ceeb nyob rau hauv niche ciaj uas muag xws li ntoo coatings thiab pem teb coatings.
Sib piv cov ntsiab lus ntawm plaub txheej txheem:
CPU txheej txheem: Qhov zoo yog nyob rau hauv customization muaj peev xwm thiab ib tug dav hardness ntau yam, haum rau elastomer Cheebtsam;
TPU txheej txheem: Cov yam ntxwv los ntawm kev ua haujlwm siab thiab tus nqi qis, txawm tias txwv los ntawm kev sib koom ua ke;
Cov txheej txheem ua npuas ncauj: Ua tiav cov rwb thaiv tsev lossis softness ua haujlwm los ntawm kev siv tshuab foaming, nrog rau daim ntawv thov dav;
Txheej txheej: Sib npaug tiv thaiv thiab kho kom zoo nkauj xav tau, ua ib qho tseem ceeb ntawm kev kho deg.
Zuag qhia tag nrho, plaub txheej txheem sib raug raws li qhov xav tau ntawm cov khoom tseem ceeb ntawm polyurethane nyob rau hauv plaub qhov ntev: elasticity, lightweighting, thermal rwb thaiv tsev, thiab tiv thaiv nto. Thaum xaiv cov txheej txheem, cov tuam txhab lag luam yuav tsum ua tib zoo xav txog yam xws li cov khoom lag luam cov kev xav tau ntawm kev siv tshuab, ntim ntau lawm, cov peev nyiaj siv, thiab qhov kawg - siv ib puag ncig, txhawm rau xaiv cov txheej txheem tsim nyog tshaj plaws thiab ua tiav qhov zoo sib npaug ntawm kev ua haujlwm thiab tus nqi.
