Cov Teeb Meem thiab Kev Dais Teeb Meem ntawm Pvc Wood Yas Wallboard

PVC phab ntsa board yog ib hom khoom PVC uas nce sai sai hauv xyoo tas los no; cov khoom muaj kev tiv thaiv ib puag ncig, zoo nkauj, tsis muaj dej noo, yooj yim teeb tsa thiab lwm yam zoo sai sai yeej cov neeg siv khoom hlub. Hauv cov txheej txheem ntawmPVC phab ntsa extrusion, qhov xwm txheej tsis zoo ib txwm muaj yog: lub rooj tsavxwm phab ntsa tsis ncaj, lub rooj tsavxwm phab ntsa tsis sib npaug, qhov chaw tsis du, qhov ceev, cov kab nthwv dej, qhov tawv tsis zoo, thiab lwm yam, ntsib cov teeb meem no peb yuav tsum daws nws li cas?

Vaj huam sib luag tsis ncaj

Ua ntej tshaj plaws, xyuas seb lub pwm thiab lub qhov ncauj pwm puas yog. Feem ntau, lub vaj huam sib luag phab ntsa raug khoov rau sab saud tej zaum vim tias lub qhov ncauj pwm thiab lub qhov ncauj pwm tsis yog, thiab qhov chaw nyob rau sab siab. Lub vaj huam sib luag phab ntsa raug khoov rau hauv qab vim tias lub qhov ncauj pwm zoo li qis.

Yog tias lub qhov ncauj pwm thiab lub qhov ncauj pwm tau sib phim, ces xyuas seb lub tank txias dej, traction thiab lub rooj pom puas sib phim nrog lub pwm.
Tom qab cov laj thawj no raug tshem tawm lawm, muaj ob qho ua rau muaj kev tsis ncaj ncees:

(1) Qhov txias ntawm cov khoom siv phab ntsa PVC tsis txaus, ua raws li lub tank dej txias tom qab qhov kub tseem siab heev, yog tias muaj lub zog sab nraud thiab kev cuam tshuam, txoj kev kho tshwj xeeb kom nce cov dej txias thiab dej txias qhov pwm lossis txo qhov kub ntawm cov dej txias, tsis txhob txo qhov ceev ntawm kev tsim khoom ncaj qha;

(2) Qhov ceev ntawm ob sab tsis sib xws, txoj kev hloov kho: kho qhov kub ntawm ob sab ntawm pwm rau tib qho kev soj ntsuam rau ib nrab teev, yog tias tsis muaj kev hloov pauv kom pom sab twg ntawm qhov ceev ntawm qhov tso tawm qeeb, sab twg ntawm qhov kub nce ob peb degrees, lossis sab twg ntawm qhov kub ntawm qhov tso tawm sai kom txo ob peb degrees.

PVC wallboard hauv zos tsis sib npaug

Feem ntau cov phab ntsa vaj huam sib luag hauv zos convex thiab concave feem ntau nyob rau hauv pwm ntawm qhov chaw tsim khoom nqus tsev. Yog tias cov degree nqus tsev tsis txaus, lossis ua tiav qhov tsim hom dej txias tsis txaus, txoj kev hloov kho yog kom nce cov dej txias hauv zos, los ntawm kev foob dej kom txhim kho qib nqus tsev, kom ua kom ceev ceev ntawm cov khoom phab ntsa. Yog tias cov dej hauv zos tsis sib npaug rau qhov siab tshaj plaws, ces cov pwm yuav raug tshem tawm kom ntxuav nws txoj kev cua tiag tiag.

Tag nrho cov nplaim ntawm phab ntsa vaj huam sib luag tsis du
Qhov laj thawj yog tias qhov kub tag nrho ntawm cov pwm siab dhau lossis lub twj tso kua mis ntawm lub extruder tsis ua haujlwm zoo. Txoj kev kho: txo qhov kub tag nrho ntawm cov pwm los ntawm ob peb degrees lossis ntxuav lub twj tso kua mis ntawm lub extruder.

Kev txhawb nqa phab ntsa tawg

Saib seb puas muaj kev puas tsuaj rau qhov dej ntawm phab ntsa. Los yog cov roj nplua nyeem hauv cov mis no nyob rau sab siab, tshwj xeeb tshaj yog qhov ntau ntawm cov roj nplua nyeem sab nraud. Los yog siv cov khoom ruaj khov qis dua, cov roj nplua nyeem sab hauv thiab sab nraud ntau dua, cov khoom tsis ruaj khov.

Qhov ceev dhau, ua npuas tsis zoo

Ua ntej tshaj plaws, saib seb qhov roj nplua nyeem puas sib npaug, qhov roj nplua nyeem ntau dhau, ua rau lub zog yaj poob qis, qhov npuas loj dua, qhov ceev yuav nce ntxiv. Dua li no, qhov ntau npaum li cas ntawm cov neeg sawv cev ua npuas ncauj tuaj yeem txo qis lossis qhov ntau npaum li cas ntawm cov neeg tswj hwm tuaj yeem nce ntxiv kom pom tias puas muaj kev cuam tshuam, thiab qhov xwm txheej tuaj yeem hloov kho raws li cov lus taw qhia.

Nto dej ntws

Qhov laj thawj tseem ceeb yog vim muaj kev tso tawm tsis sib xws, ua rau muaj kev tso tawm tsis sib xws yog: ntau dhau plasticizing yaj mos dhau; cov khoom ntws tsis sib xws; traction thiab extrusion mismatched; lub zog yaj siab dhau thiab rov qab los.

Peb tuaj yeem daws qhov teeb meem no los ntawm cov hauv qab no:

I. Txheej Txheem:

1) Txo qhov ceev ntawm kev tsim khoom, xws li qhov ceev ntawm cov ntsia hlau, qhov ceev ntawm kev pub mov, thiab lwm yam, thiab kho qhov ceev ntawm kev rub kom haum; qee zaum hauv kev tsim khoom cov kab wavy ploj mus los ntawm kev kho lawv li no.

2) Txo qhov kub ntawm extrusion, tshwj xeeb tshaj yog qhov kub ntawm cov yas seem hauv thaj chaw thib peb thiab thib plaub. Lub clapboard uas nws tus kheej tsim tam sim no ntau lub tuam txhab siv cov raj me me maester, qauv hlau maester lossis cov ntawv ua npuas ncauj maester los ua cov khoom, cov maester no koom nrog ob zaug txheej txheem maester, plasticize yog ceev heev, txo cov yas kom tsim nyog thiab cov khoom ruaj khov muaj qee qhov zoo.

II. Cov Khoom Siv:

1. Kho qhov sib txawv ntawm lub hau ntswj, txo qhov shear kom haum, thiab qeeb qeeb plasticizing;

2. Ntxuav lub taub hau tuag thiab txhuam nws, tshwj xeeb tshaj yog ntawm ob qho kawg ntawm lub pwm, kom cov khoom yaj ntws zoo.

3. Xyuas kom tseeb tias cov pwm muaj teeb meem, xws li tsis nco qab ntsia lub pin positioning, lossis seb puas muaj teeb meem nrog lub hau ntswj, xws li lub plawv sib txawv, uas yuav ua rau cov khoom ntws tsis zoo, feem ntau tsuas yog nyob rau sab ntawm cov qauv nthwv dej ntawm cov khoom siv, thiab nws nyuaj rau tshem tawm los ntawm kev kho cov mis.

III. Tus qauv:

1. Ua kom cov roj sab nraud ntau ntxiv, txo cov roj sab hauv, tab sis tsis txhob hloov kho ntau dhau

2. Tsis txhob cuam tshuam rau qhov ua npuas ncauj, tus tswj kev ua npuas ncauj tuaj yeem tsim nyog los txo lossis xaiv tus tswj kev ua npuas ncauj nrog lub zog yaj me me, qhov xwm txheej no tsuas yog txwv rau qhov xwm txheej ntawm lub zog yaj loj dhau, los tiv thaiv cov khoom tawm ntawm lub pwm vim lub zog yaj loj dhau rebound, tsim cov kab nthwv dej.

Kev nyuaj siab yog qhov tsis zoo

Thawj qhov yog siv cov khoom siv hlau yas ntau dhau, cov khoom siv raj me me thiab lwm yam khoom siv theem nrab. Qhov thib ob, xav txog seb qhov ntau ntawm cov roj nplua nyeem sab nraud ntau dhau, tshwj xeeb tshaj yog siv cov stabilizer pheej yig, kom tsis txhob nplaum, qhov ntau yuav nce, yuav ua rau cov mis tag nrho ntawm cov roj nplua nyeem sab nraud ntau dhau. Dua li xav txog seb cov khoom siv PVC puas muaj plasticization, plasticization tsis zoo lossis plasticization ntau dhau yuav ua rau cov khoom tawg. Thaum kawg, yog tias cov teeb meem no raug tshem tawm lossis qhov toughness tsis txaus, tus hloov kho toughening CPE-135A tuaj yeem ntxiv rau qhov tsim nyog.

Hauv cov txheej txheem tsim khoom ntawm PVC phab ntsa, yuav tsum tau them sai sai rau qhov xwm txheej ntawm cov khoom siv, kev noj qab haus huv ib puag ncig thiab kev qhuab qhia. Cov xwm txheej ntawm cov khoom siv yuav tsum tau sau tseg raws li hauv qab no:

(1) Seb tus tswv tsev tam sim no thiab lub qhov ntswg siab puas tsim nyog;
(2) Seb qhov kub ntawm lub tswj qhov kub thiab txias thiab txhua lub ammeter puas tuaj yeem ua haujlwm li qub;
(3) Seb qhov kub ntawm lub cev muaj zog tseem ceeb thiab lub thawv txo qis puas siab dhau;
(4) Seb lub twj tso kua mis puas yog qhov qub;
(5) Seb lub thermocouple ntawm lub pwm puas tuaj yeem ntxig rau qhov kawg (6) seb dej thiab hluav taws xob puas zoo li qub.
