Txhawb tshuaj

Tom qab lub silica gel npaj, nws yuav tsum tau molded nyob rau hauv lub sij hawm. Ncuav cov silicone rau hauv qhov siab tshaj plaws ntawm lub pwm los ntawm trickle, cia nws ntws lawm, thiab siv cov roj txhuam kom muab tso rau hauv qhov chaw. Yog hais tias nws yog ib qho ntawm cov mold silicone, tsis tsuas yog tag nrho cov khoom tab sis kuj lub kua nplaum yuav tsum sib npaug brushed. Txhua qhov khoom yog brushed yam tsawg peb txheej ntawm silica gel. Lub thickness ntawm txhua txheej ntawm silica gel yog 1 hli. Nyob rau hauv txoj kev ntawm txhuam silica gel, txhua txheej yuav tsum tau kho kom zoo ua ntej txhuam lwm txheej. Thaum txhuam ntawm txheej txheej thib peb, ntxiv ib txheej rau txheej ob. Tag nrho pwm silicone ib feem yog tswj rau 3-4 hli nyob ntawm seb qhov loj me ntawm cov khoom, thiab dav tsis tshaj 60 hli. Lub silicone pib teem nyob rau hauv 20 feeb.


1. Ntxuav thiab qhuav cov pwm moj pliav rau qhov pam (koj tuaj yeem siv daim ntawv tso quav tawm los yog siv cov pwm tso tawm)


2. 500-1000 grams pwm silicone rubber (pwm silicone, pwm kua nplaum, kua roj hmab silicone, silica gel) raws li lub hnab yas qaub ncaug;


3. Lub tshuab hnyav yog ntsuas raws li qhov nyhav (feem ntau yog 1.5-2.5%), ces ntxiv rau lub khob rau kom tov, thiab tag nrho cov khoom sib tov;


4. Ntxiv qee qhov ntawm silica thias nyob ntawm qhov teeb meem no (tshwj xeeb tshaj yog thawj txheej) kom txog rau thaum nws sib xyaw ua ke, feem ntau yog 3-5 nas this.


5. Tom qab sib tov cov pwm silicone pwm (pwm silicone, pwm kua nplaum, kua roj hmab silicone, silica gel) nrog lub tshuab zom zaws, qhov tshuaj tiv thaiv yog nyob rau hauv chav tsev sov, thiab cov kua qaub qis tsis zoo yog tso tawm. Yuav kom tshem tawm cov cawv molecules los ntawm lub colloid, nws yog ib qhov tsim nyog yuav tau tawm cov npuas raws li qhov tsis pom kev siab. Kuj yuav siv tau yam tsis muaj cov khoom siv (mas nyob ntawm seb cov khoom siv kev ua haujlwm zoo li cas)


6, Thaum twg tus nqi ntawm tus neeg sawv cev curing qis dua, lub sij hawm ua kom ntev, qhov tshuaj tiv thaiv yog txaus, thiab qhov khoob zoo yog qhov zoo. Yog li, tus nqi ntawm tus neeg sawv cev curing zoo dua li sab hauv. Thaum txhuam yog siv, thawj txheej (sab hauv txheej) yog qhuav thiab ces ob txheej yog brushed. Lub sij hawm ua hauj lwm yog 30-50 feeb, thiab lub sij hawm demoulding yog 10-15 teev. Kauj sijhawm yog 24 xuab moos. Nco ntsoov tias tom qab thawj thiab thib ob cov txheej txheem thov, nws zoo dua ntxiv cov ntaub pwm, uas tuaj yeem txhim kho lub neej pwm ntawm cov pwm (tab sis lub iav fiber ntaub siv tsis tau, txwv tsis pub nws yuav yooj yim ua rau delaminating thiab tag nrho pwm yuav tsum tau tseg)


7. 3D perfusion pwm, feem ntau 10-15 teev ntawm kev kho kom zoo.


8. Tom qab cov pwm mos tas lawm, ua lub plaster los yog FRP tsho los pab txhawb cov pwm ntawm cov kua pliav. Lus Cim: 1. Pwm xaiv qhov xaiv: xaiv qhov chaw uas tsis cuam tshuam dab tsi ntawm qhov khoom; xaiv txoj hauj lwm uas yooj yim ua kom tiav tom qab grouting; xaiv cov pwm nws tus kheej yog ib qho yooj yim los rhuav tau txoj hauj lwm ntawm cov pwm; xaiv qhov chaw uas qhov khoom tsis yog yooj yim deformed. 2. Tsis txhob ua kom qhov muag tsis pom muaj zog ntxiv rau qhov khoom siv sijhawm ntau; txwv tsis pub cov kev pab cuam lub neej ntawm silicone mould yuav raug zoo heev.
