Tshaj Tawm Cov Neeg Sawv Cev thiab Cov Txheej Txheem Tshaj Tawm hauv Kev Lag Luam Sib Txawv
Txheej txheem cej luam ntawm Cov Neeg Tso Tawm
Tus neeg tso tawm, tseem hu ua tus neeg tso tawm, tus neeg tso tawm. Nws yog txheej txheej txheej ntawm cov pwm thiab cov pwm pwm, uas tuaj yeem ua rau saum npoo ntawm cov khoom yooj yim tso tawm, du thiab huv.
Yuav ua li cas tso tus neeg sawv cev ua haujlwm
▶ Cov tshuaj tiv thaiv kab mob polar cuam tshuam nrog pwm nto los ua ib zaj duab xis absorbent.
▶ Thaum nthuav tawm mus rau hauv ib qho kev sib koom ua ke ntawm cov pwm saum npoo, cov molecules txais yuav cov yam ntxwv ncab saw teeb.
Them rau hauv cov khoom ntim duensely, nrog nce molecular hnyav thiab viscosity tsis pub dhau ib qho, kev tso tawm muaj peev xwm nce.
Vim muaj qhov sib txawv ntau lawm, ntau qhov yuav tsum tau muab tso rau pem hauv ntej rau kev ua haujlwm ntawm tus neeg sawv cev tso tawm. Raws li txoj cai, tus neeg sawv cev tso tawm yuav tsum muaj cov yam ntxwv xws li tshuaj tiv thaiv corrosion, kub tsis kam, hnav tsis kam thiab tensile lub zog, zoo tso tawm txuas ntxiv, tsis muaj kuab paug rau pwm, thiab tsis muaj kev hloov pauv theem nrab.
Tso daim ntawv thov tus neeg sawv cev
Nrog txoj kev loj hlob sai ntawm kev txhaj tshuaj molding, extrusion, calendering, molding, lamination thiab lwm yam txheej txheem, tus nqi tso tawm kuj tau nce ntau. Pwm tso tawm cov neeg ua haujlwm tau siv dav hauv cov txheej txheem molding ntawm cov khoom sib xyaw xws li hlau, roj hmab yas, pob zeb, polyurethane, carbon fiber, unsaturated resin, epoxy, phenolic, vinyl resin, thiab lwm yam.
Casting yog txheej txheem uas cov hlau smelted rau hauv cov kua uas ua tau raws li qhov yuav tsum tau ua thiab nchuav rau hauv pwm. Tom qab txias, solidification, thiab tu, ib tug casting (ib feem los yog dawb paug) nrog ib tug predetermined zoo, loj thiab kev ua tau zoo yog tau.
Casting yog muab faib ua gravity casting thiab siab casting (tuag casting) raws li cov txheej txheem casting ntawm molten hlau.
Lub ntiajteb txawj nqus casting muaj xws li xuab zeb casting (ntsuab xuab zeb, qhuav xuab zeb, chemically hardened xuab zeb) casting, hlau casting, peev casting, poob ua npuas ncauj casting, thiab lwm yam.; siab casting yog hais txog cov txheej txheem ntawm kev txhaj tshuaj molten hlau rau hauv pwm nyob rau hauv qhov kev txiav txim ntawm lwm yam sab nraud quab yuam.
Nyob rau yav qab teb cheeb tsam ntawm kuv lub teb chaws, dej-muaj emulsified hydrocarbon hnyav roj feem ntau yog siv rau demoulding nyob rau hauv ntsuab xuab zeb casting, uas tsis tsuas yog txo cov nqi tsim, tab sis kuj tshem tawm cov muaj peev xwm kev nyab xeeb txaus ntshai tshwm sim los ntawm flammability thiab tawg ntawm hydrocarbon hnyav roj. . Nyob rau hauv lub caij ntuj no nyob rau hauv sab qaum teb cheeb tsam, uas tsis yog-dej hydrocarbon solvent roj cov khoom yog feem ntau yog siv los tiv thaiv cov khoom los ntawm freezing nyob rau hauv qis kub thiab tsis ruaj tsis khov.
Tus neeg sawv cev tuag-casting feem ntau yog cov txheej txheem sib xyaw ntawm silicone emulsion, wax emulsion, fatty acid ester emulsion, thiab lwm yam. Lub synergistic compounding ntawm ntau yam emulsions enables tus neeg tso tawm kom muaj lubrication zoo thiab hlau infiltration cuam tshuam nyob rau hauv kub kub.
Cov tub ntxhais kub lub thawv molding xuab zeb tso tawm tus neeg saib xyuas thiab cov tub ntxhais txias lub thawv molding xuab zeb tso tawm tus neeg saib xyuas siv cov khoom sib txawv ntawm cov khoom siv silicone raws li cov pwm tso tawm raws li cov txheej txheem sib txawv.
Forging tso tawm cov neeg ua haujlwm ua lub luag haujlwm tseem ceeb hauv cov txheej txheem yas tsim ntawm carbon steel, alloy steel, aluminium, magnesium, titanium, tooj liab, thiab lwm yam thiab lawv cov alloys.
Tsoos forging tso tawm cov neeg ua haujlwm feem ntau yog tshem tawm cov hmoov tsis zoo xws li graphite, carbon hmoov, talc hmoov, molybdenum disulfide thiab binders, uas suav nrog feem ntau ntawm cov roj forging. Nrog rau kev ua kom muaj kuab paug loj zuj zus ntxiv, tsis yog-graphite ib puag ncig tus phooj ywg forging tso tawm cov neeg ua haujlwm tau maj mam nce thiab siv hauv kev ua lag luam hauv kev tsim cov tooj liab, carbon hlau, txhuas, stainless hlau thiab lwm yam hlau.
Liquid tuag forging (nqus extrusion casting) feem ntau yog ib qho kev ncua ntawm inorganic hmoov raws li lub ntsiab tivthaiv, supplemented los ntawm ib tug me me npaum li cas ntawm wax emulsion, tackifying resin, thiab lwm yam. qhov txias ua ntej ntawm cov hlau molten thiab tsis tiav txias cais hom ntawm cov casting.
Nyob rau hauv Suav teb, uas muaj lub npe ntawm "infrastructure maniac", nws cov ntaub ntawv tseem ceeb infrastructure yog reinforced pob zeb. Hom kev tso tawm no feem ntau yog koom nrog hauv kev tsim cov pob zeb thiab cov khoom cement xws li cov neeg pw tsaug zog, taug kev slabs, txuas hniav, piers, kav dej, ntu, cov yeeb nkab, thiab cov tsev prefabricated. Mineral roj, roj cav, roj ester emulsion, fatty acid xab npum los yog cov khoom siv hnyav feem ntau yog siv los ua kom tau raws li cov kev xav tau ntawm ntau yam xws li pwm sib txawv, climatic tej yam kev mob, kev tsim kho, cov nqi ntawm cov khoom, thiab cov tsos zoo ntawm cov khoom ua vaj tse.
Yas thiab roj hmab pwm tso tawm cov neeg ua haujlwm feem ntau siv cov tshuab silicone, ntawm cov yas pwm tso tawm cov neeg ua haujlwm feem ntau yog cov tshuaj tsuag-tau-hom silicone diluents. Cov roj hmab tso tawm cov neeg ua hauj lwm tau muab faib ua cov yeeb yaj kiab, hoses thiab cov log tsheb tso tawm cov neeg ua haujlwm, thiab cov pwm tso tawm cov neeg ua haujlwm tau siv rau hauv cov txheej txheem tsim cov log tsheb. Cov neeg ua yeeb yaj kiab tso tawm yog feem ntau fatty acid xab npum hmoov thiab inorganic hmoov, uas yog tus nqi qis, tab sis yooj yim ua rau plua plav paug thaum tsim khoom. Muab cov yeeb yaj kiab tso tawm, cov roj hmab butyl lossis cov roj hmab hauv lub raj tso tawm cov neeg ua haujlwm zam cov teeb meem no. Polyether thiab polyester tuaj yeem siv los ua cov pwm tso tawm rau cov roj hmab hoses vim lawv cov khoom tu zoo thiab tsis muaj qhov seem.
Tire tso tus neeg saib xyuas (tso tawm tus neeg saib xyuas), uas tuaj yeem pleev xim rau ntawm lub zais zis lossis lub log tsheb embryo. Vim yog qhov yuav tsum tau nruj me ntsis ntawm cov pwm tso tawm thiab pwm tso tawm txuas ntxiv, nws yog ib qho tsim nyog yuav tsum siv reactive silicone emulsion thiab silicone resin emulsion rau pwm tso tawm, txau Ib zaug, nws tuaj yeem ua tiav 12 sib law liag demoulding. Silicone roj hmab tso cov neeg ua hauj lwm yuav tsum siv fluorine-muaj surfactants, fluorine-muaj polyethers, thiab lwm yam nyob rau hauv xaiv cov khoom raw cov ntaub ntawv.
Cov khoom siv polyurethane yog siv ntau ntau thiab muaj ntau hom, suav nrog polyurethane mos ua npuas ncauj, ua npuas ncauj nruj, tawv nqaij polyurethane, polyurethane microcellular elastomer, siab resilience polyurethane, thiab lwm yam. Cov khoom no yog dispersed nyob rau hauv dej raws li siv quav ciab emulsion, hloov silicone. roj emulsion, thiab hnyav-raws li siv quav ciab. ua kua.
Tso tus neeg sawv cev rau cov khoom sib xyaw
Lub teb ntawm cov ntaub ntawv sib xyaw yog dav heev, thiab cov khoom muaj xws li cov pob zeb dag, SMC (daim ntawv molding compound), lub kaus mom hlau tsis muaj phom, chav dej, cov khoom siv roj carbon fiber ntau, epoxy kuj, epoxy reactance, yacht, kiv cua, lub hau npog, caij ski, rotomolding. , hluavtaws Fiber... npog cov ntaub ntawv xws li epoxy, phenolic, unsaturated resin, vinyl resin, thiab lwm yam. Feem ntau ntawm cov ntaub ntawv saum toj no siv cov khoom siv emulsion los yog fatty acid ester, surfactant, thiab lwm yam.
