Silicon compound yog cov khoom siv zoo tshaj plaws rau kev ua pwm rau pob txha, lifecasts thiab lwm yam khoom tawv. Raws li cov kua latex, nws muab lub teeb, hloov tau, siab fidelity zoo. Nws kuj muaj cov txiaj ntsig ntxiv ntawm kev ua neej ntev thiab ua haujlwm rau cov tshuaj thiab degradation. Nws yog cov khoom pom zoo rau kev ua cov pwm ruaj khov los ntawm cov qauv tseem ceeb. Gypsum silicone pwm tuaj yeem ua rau lub sijhawm tsawg dua li cov pwm latex yog tias siv "ceev" catalysts. Qhov tsuas yog qhov tsis zoo yog tias nws kim dua li latex thiab tsis zoo li qub, ua rau tawg thiab puas.

Cov khoom siv silicone

Cov khoom siv no muaj cov tshuaj silicone ua lub hauv paus thiab platinum catalyst uas ua kom nrawm nrawm.

Thaum tsim pwm, silicone compound yog siv pob tshab, liab, daj, dawb thiab lwm yam xim. Lub hardener kuj tseem muaj cov palette sib txawv lossis tsis muaj xim.

Tom qab sib tov ob yam khoom ntawm chav tsev kub, cov khoom siv silicone ua kom khov thiab ua rau cov roj hmab zoo li qub. Lub sijhawm kho rau feem ntau yog nyob nruab nrab ntawm 18-24 teev, tab sis lub sijhawm kho tuaj yeem txo qis heev los ntawm kev siv cov catalysts ceev ceev.

Hom ntawm silicone compounds

Cov roj hmab feem ntau siv los ua pwm yog RTV, RTV-2 thiab HTV. Tsis zoo li RTV (chav kub vulcanizing) roj hmab, HTV silicone yuav tsum tau kub tshaj 100 ° C los kho.

Ntawm cov neeg ua cov khoom siv silicone, txhua tus sim ua ntau yam silicones thiab catalysts nrog sib txawv viscosities, xim thiab lwm yam haujlwm.

Muaj ob chav kawm tseem ceeb ntawm RTV silicones

1. Tin catalyzed silicones.

2. Silicones ntawm platinum catalysts.

Txhua ntawm lawv muaj nws qhov zoo thiab qhov tsis zoo. Tin-catalyzed silicones feem ntau pheej yig dua thiab siv yooj yim dua. Lawv muaj viscosity tsawg mus rau nruab nrab, yog li lawv ntws zoo nyob ib ncig ntawm cov khoom. Nyob rau hauv sib piv, platinum yog suppressed los ntawm ntau ib txwm tshwm sim tebchaw, tshwj xeeb tshaj yog sulfur, tin, amines, freshly ua polyester, epoxy los yog urethane roj hmab khoom. Txawm tias tom qab txheej cov khoom nrog acrylic varnish, silicone compound rau pwm rauplatinum yuav tsis tawv thaum muaj kev cuam tshuam nrog sulfur- thiab tin-muaj qhov chaw. Qhov no ua rau lawv tsis haum rau ntau yam khoom ntuj tsim. Txawm li cas los xij, ib zaug kho tau, lawv muaj cov tshuaj zoo tshaj plaws, microbiological thiab kub tsis kam thiab feem ntau nyob twj ywm rau ntau xyoo. Nyob rau hauv sib piv, tin-catalyzed silicones yuav ua nkig tom qab ob peb xyoos ntawm kev siv thiab pib sib cais los yog tsim kua muag. Rau cov laj thawj no, silicones nyob rau hauv pawg tin feem ntau yog siv rau cov haujlwm uas tsis tshua muaj suab nrov. Thiab platinum yog siv rau kev ua haujlwm tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ntim loj.

Txuag lub neej

Ntau cov silicones tuaj yeem siv tau zoo txog 5 xyoos txij li hnub ntawm kev yuav khoom yog tias khaws cia hauv cov thawv ntim cua hauv qhov chaw qhuav, txias. Txawm li cas los xij, catalysts poob lawv cov txiaj ntsig sai sai, txawm tias khaws cia kom zoo lawv tau siv zoo tshaj plaws hauv ib xyoos.

Qhov twg thov

RTV-2 silicone compound yog siv los ua cov ntawv luam ntawm ntau yam duab. Raws li cov khoom kos duab ua los ntawm polyester, epoxy resins, wax, plaster, tswm ciab, khoom ua si thiab xab npum, thiab lwm yam.

Pentelast silicone compound yog qib zaub mov thiab nyab xeeb. Qhov zoo ntawm cov khoom siv no yog tias nws hloov tau yooj yim heev thiab tsis ua rau cov khoom puas tsuaj thaum tshem tawm, cov pwm no tuaj yeem rov qab siv dua. Xav tias qhov no yog cov zaub mov qib silicone ntawm platinum catalyst, nws tuaj yeem siv los uasilicone pwm rau plaster, pwm rau ncuav mog qab zib thiab cupcakes, pastries thiab lwm yam confectionery.

qhia kev nyab xeeb

Silicon compound yog ib yam khoom muaj kev nyab xeeb thiab tsis muaj ntxhiab thaum siv kom raug, txawm li cas los xij cov catalysts thiab thickeners tuaj yeem ua rau lub qhov muag thiab tawv nqaij, yog li cov khoom ntawm lub cev yuav tsum tau tiv thaiv.

txheej txheem tsim pwm

• Qhov saum npoo ntawm cov qauv luam tau raug ntxuav thiab degreased. Yog tias tsim nyog, siv wax lubricant, tshuaj xab npum lossis roj av jelly.
• Cov khoom sib xyaw kom huv si vim tias cov av tuaj yeem tsim thaum lub sijhawm khaws cia.
• Ib lub thawv tau npaj ua ntej, nyob rau hauv uas lub hauv paus rau lub tswv yim yog muab tso rau. Xws li lub thawv tuaj yeem yog lub khob yas, lub raj mis lossis lub thawv. Nws yuav tsum muaj qhov ncaj ncaj hauv qab thiab sab yam tsis muaj qhov qhib lossis qhov.

• Nyob rau hauv ib lub thawv huv, lub hauv paus nrog hardener yog diluted kom txog thaum ib homogeneous loj tsim.

• txhawm rau kwv yees tus nqi ntawm silicone yuav tsum tau, koj yuav tsum xam cov ntim ntim kom cov khoom ntim tag nrho. Lwm qhov kev xaiv - koj tuaj yeem tsuas npog qhov chaw ntawm cov khoom nrog rau qhov thiab kev nyuaj siab, tom qab hardening ncuav lwm feem ntawm silicone, qhov no silicone thiab nyiaj tau txais kev cawmdim. Txhawm rau kom sib npaug ntawm cov qauv, nws yog qhov tsim nyog los ncuav lossis siv cov silicone hauv ob lossis ntau pawg. Qhov thib ob batch yog siv rau sab saum toj ntawm hardened thawj, tab sis tseem nplaum. Ua taukuj tseem siv gauze los yog lwm yam ntaub ntawv uas yuav tsum tau embedded nruab nrab ntawm cov khaubncaws sab nraud povtseg, uas tso cai rau koj mus ua ib tug ntau check daim ntawv.
• Catalysts yog sib xyaw ua ke nyob ntawm seb hom silicone. Ib txhia ntawm lawv siv lub hauv paus rau catalyst piv ntawm 50:50. Koj tuaj yeem sib tov mechanically lossis manually nrog rab diav lossis stick. Koj tuaj yeem tsis tuaj yeem koom nrog cov txheej txheem no ntev ntev tsis pub dhau 2 feeb, txij li cov txheej txheem ntev ua kom muaj cua npuas ntau hauv qhov sib tov. Yuav kom paub seb puas muaj qhov sib xws tau txais, nws yog qhov zoo dua los siv cov xim tawv tawv.
• Tom qab sib tov, qhov loj yog nchuav tawm sai li sai tau. Cov ntaub ntawv kho mob rau lub xeev rubbery hauv 24 teev. Thaum kub hauv qab +23 ° C, lub sijhawm kho yuav ntev dua.

Yam yuav tsum xav txog

Huab cua npuas tuaj yeem txo kom tsis muaj dab tsi los ntawm thawj zaug sib xyaw me me ntawm cov khoom sib tov thiab siv txhuam los npog cov qauv nrog nws. Nyob rau hauv txoj kev no, tsis tsuas yog qhov kev tshem tawm ntawm npuas ua tiav, tab sis kuj yog qhov tseeb ntawm cov qauv ntawm daim ntawv. Tom qab siv cov txheej nyias nyias, cia cov khoom nyob ib leeg ntawm chav tsev kub kom txog thaum sib tov tsis muaj cua thiab pib tawv. Tom qab ntawd cov seem ntawm cov hardener yog tov nrog lub hauv paus thiab siv rau hauv cov khaubncaws sab nraud povtseg rau cov khoom kom txog rau thaum tau txais daim ntawv tiav. Hauv chav kuaj, cov txheej txheem no yooj yim dua, raws li nws tau ua tiav siv cov tshuab uas co cov pwm thiab tso tawm cua. Hauv av av, koj tuaj yeem co los ntawm kais ntawm koj tus kheej.

Yog cov qauv tsis muaj ntujCiam teb kom tiv thaiv cov silicone los ntawm kev ntws thaum lub sij hawm nchuav, ib phab ntsa tuav yuav tsum tau ua nyob ib ncig ntawm cov qauv. Qhov no tuaj yeem ua tiav nrog cov khoom siv tsis zoo xws li ntoo planks, clapboard, cardboard, thiab lwm yam. Koj tuaj yeem kho thiab kaw cov phab ntsa nrog cov nplaum nplaum kom cov silicone tsis nkag los ntawm cov kab nrib pleb.

Nco ntsoov! Qee hom silicone tej zaum yuav txawv me ntsis ntawm qee hom pob zeb uas tau nrum. Ua ntej ua haujlwm, nws raug nquahu kom sim thiab sim nrog cov qauv tsis tseem ceeb ua ntej siv cov khoom muaj txiaj ntsig.
