Polyurethane foaming tshuab yog dav siv hauv kev tsim kho, rwb thaiv tsev, ntim khoom, rooj tog thiab lwm yam. Txawm li cas los xij, vim nws txoj kev siv tshuab ua haujlwm nyuaj thiab cov tshuaj tiv thaiv tshuaj, cov cuab yeej yuav ntsib ntau yam teeb meem.
Tej teeb meem thiab kev daws teeb meem
- Nyuaj hauv kev pib cov cuab yeej: Ua ntej xyuas seb qhov kev sib txuas ntawm lub hwj chim puas zoo li qub, thiab tom qab ntawd xyuas seb qhov kev nyab xeeb ntawm cov cuab yeej puas zoo li qub. Yog tias cov khoom siv nyob rau hauv lub xeev overheated los yog overloaded, tos kom cov khoom txias thiab xyuas kom meej tias tag nrho cov seem tau rov pib dua.
- Cov phom phom raug thaiv: Tshem cov phom phom thiab ntxuav nws nrog cov kuab tshuaj tsim nyog. Xyuas kom tseeb tias tsis muaj pob los yog cov seem nyob hauv rab phom thiab cov kav dej.
- Kev sib xyaw ua kua tsis sib xws: Tshawb xyuas cov kua xa tawm thiab cov khoom sib tov kom paub tseeb tias lawv txhua tus ua haujlwm zoo. Yog tias cov kua tsis sib tov sib npaug, xyuas seb cov kua mis puas yog.
- Cov teeb meem tsim ua npuas ncauj: Yog tias muaj teeb meem nrog kev tsim ua npuas dej, xyuas seb qhov piv ntawm cov neeg ua npuas ncauj thiab cov khoom siv hluav taws xob puas yog. Tsis tas li ntawd, xyuas seb lub tshuab cua sov ntawm cov khoom siv puas ua haujlwm zoo, vim tias qhov kub thiab txias muaj kev cuam tshuam zoo rau lub sijhawm ua npuas dej.
- Cov khoom siv tsis ruaj khov: xyuas seb lub tshuab hydraulic thiab pneumatic ntawm cov khoom puas ruaj khov. Yog hais tias lub kaw lus siab fluctuates heev, lub siab tswj valve yuav tsum tau kho.
Kev daws thiab cov lus qhia
- Rau cov cuab yeej pib teeb meem, kev saib xyuas cov cuab yeej tuaj yeem ua tau tsis tu ncua, suav nrog kev kuaj xyuas lub zog sib txuas, cov cuab yeej kev nyab xeeb, thiab cov khoom tiv thaiv overload.
- Rau cov teeb meem ntawm rab phom clogging, rab phom thiab cov raj xa dej tuaj yeem raug ntxuav tam sim ntawd tom qab siv txhua zaus, thiab cov phom phom lim tuaj yeem kuaj xyuas thiab hloov tsis tu ncua.
- Rau qhov teeb meem ntawm kev sib xyaw ua kua tsis sib xws, cov kua xa tawm thiab cov khoom sib tov tuaj yeem kuaj xyuas tsis tu ncua, thiab cov kua mis tuaj yeem hloov kho raws li cov chaw tsim khoom cov lus qhia.
- Rau cov teeb meem tsim ua npuas ncauj, qhov piv ntawm foaming tus neeg sawv cev thiab catalyst tuaj yeem kuaj xyuas, thiab cov khoom siv cua sov tuaj yeem tswj tau tsis tu ncua.
- Rau qhov teeb meem ntawm kev ua haujlwm tsis ruaj khov, cov tshuab hydraulic thiab pneumatic tuaj yeem kuaj xyuas tsis tu ncua, thiab lub siab tswj valve tuaj yeem hloov kho raws li cov chaw tsim khoom cov lus qhia.
Kev ua haujlwm ib txwm ntawm polyurethane foaming tshuab yog qhov tseem ceeb rau ntau daim ntawv thov kev lag luam. Los ntawm kev nkag siab thiab siv cov txheej txheem daws teeb meem thiab cov kev daws teeb meem uas tau muab rau hauv tsab xov xwm no, cov neeg ua haujlwm tuaj yeem daws cov teeb meem feem ntau uas yuav ntsib nrog cov khoom siv, yog li zam kev cuam tshuam ntau lawm thiab cov khoom lag luam tsis zoo. Txawm li cas los xij, yog tias qhov teeb meem dhau ntawm qhov uas tau teev tseg hauv tsab xov xwm no, nws raug nquahu kom tus neeg teb xov tooj nrhiav kev pab los ntawm cov chaw tsim khoom lossis tus kws tshaj lij kev pabcuam.
Peb pom zoo kom cov neeg ua haujlwm tsis tu ncua ua cov khoom tu thiab tshuaj xyuas, suav nrog tab sis tsis txwv rau cov hauv qab no:
- Kev tshuaj xyuas txhua hnub: Ua ntej pib ua haujlwm, xyuas kom txhua qhov chaw ntawm cov khoom siv ua haujlwm zoo, suav nrog kev sib txuas hluav taws xob, cov khoom siv kev nyab xeeb, cov kav dej ua kua thiab roj, thiab lwm yam.
- Kev tshuaj xyuas txhua hli: Ua ib qho kev tshuaj xyuas cov cuab yeej siv ib hlis ib zaug, suav nrog cov kav dej ua kua thiab roj, cov ntxaij lim dej, cua sov, thiab lwm yam.
- Kev tshuaj xyuas ib xyoos ib zaug: Ua ib qho kev saib xyuas thiab tshuaj xyuas cov khoom siv ib xyoos ib zaug, suav nrog kev hloov cov khoom hnav, ntxuav cov khoom siv sab hauv, thiab lwm yam.
Tsis tas li ntawd, cov neeg ua haujlwm yuav tsum nco ntsoov ua tib zoo saib xyuas cov kev tsim kho tshiab thiab kev txhim kho thev naus laus zis hauv kev lag luam, vim tias cov no tuaj yeem cuam tshuam rau txoj kev siv khoom thiab kev tswj xyuas. Piv txwv li, lub zog tshiab -txuag thev naus laus zis lossis cov khoom ua kom muaj zog ntau dua tuaj yeem hloov pauv cov kev ua haujlwm thiab kev saib xyuas cov khoom siv. Los ntawm kev ua raws li cov thev naus laus zis tshiab thiab kev paub tshiab, cov neeg ua haujlwm tuaj yeem tswj hwm thiab ua kom zoo dua qhov kev ua tau zoo ntawm lawv cov tshuab polyurethane foaming.
Feem ntau, nrog kev saib xyuas kom zoo thiab cov tswv yim daws teeb meem, cov neeg ua haujlwm tuaj yeem xyuas kom meej tias lub tshuab polyurethane foaming yog ib txwm ua haujlwm zoo, yog li muab kev txhawb nqa ruaj khov thiab muaj txiaj ntsig rau lawv cov ntawv thov kev lag luam.
