Cov Khoom Muag Ntawm Lub Hnab Ua Tsis Txaus Siab Uas 90 feem pua ​​​​ntawm cov chaw ntim khoom yooj yim tau ua, Koj puas muaj lawv?

Cov lus nug ntawm lub hnab ua yuam kev uas 90 feem pua ​​​​ntawm cov chaw ntim khoom hloov pauv tau ua, koj puas muaj lawv?

Kev ua lub hnab ntim khoom yog cov txheej txheem kawg hauv kev tsim khoom thiab ua cov khoom ntim yas hloov tau yooj yim. Yog tias qhov zoo ntawm lub hnab ntim khoom tsis tsim nyog lossis kev siv ntau dhau, ces nws yuav sib npaug rau qhov tsis ua haujlwm ntawm ntau cov txheej txheem dhau los, thiab nws yuav muaj kev cuam tshuam loj rau kev tsim khoom thiab kev ua haujlwm ntawm lub tuam txhab vim kev thov los ntawm cov neeg siv khoom. . .

1. Kuv yuav ua li cas yog tias qhov kub ntawm lub hnab ntim tshuab ua tsis tiav thiab cov ntsiab lus xau los yog deteriorate?

Yog vim li cas: Cov khoom siv hluav taws xob tiv thaiv hluav taws xob ntawm cov yeeb yaj kiab tsis zoo, feem ntau vim tias cov resin siv rau hauv cov txheej sealing sab hauv tsis haum.

Countermeasure: Siv ib zaj duab xis nrog zoo tiv thaiv kev ua qias tuaj thaum tshav kub kub sealability. Feem ntau hais lus, LDPE muaj qhov nruab nrab los tiv thaiv kev ua qias tuaj thaum tshav kub kub-sealability, EVA muaj cov khoom zoo los tiv thaiv kev ua qias tuaj thaum tshav kub kub-seal zog thaum VA cov ntsiab lus loj, LDPE kuj muaj cov khoom zoo los tiv thaiv kev ua qias tuaj thaum tshav kub kub sealing, thiab ionic resins thiab metallocene polymers muaj qhov zoo. anti-pollution tshav kub-seal zog. Nws muaj kev tiv thaiv kev ua qias tuaj thaum tshav kub kub sealability.

2. Kuv yuav ua li cas yog tias lub foob ntawm lub hnab ua tshuab yog nkig thiab nkig?

Yog vim li cas: (1) Lub tshav kub sealing kub yog siab dhau lawm; (2) Lub siab siab dhau lawm; (3) Lub sij hawm sib khi thaum tshav kub kub ntev dhau lawm; (4) Lub ntug ntawm lub sealer sab sauv yog ntse dhau los yog cov coated PTFE puas lawm; (5) Cov roj hmab silicone kaw hauv qab yog qhov nyuaj dhau; (6) Thaum lub sij hawm sib xyaw thiab kho cov txheej txheem, ib feem ntawm cov nplaum nkag mus rau hauv cov yeeb yaj kiab sab hauv. Vim yog qhov cuam tshuam ntawm kev nkag mus ntawm cov nplaum, qhov toughness (kev cuam tshuam tsis kam) ntawm cov substrate txo qis thiab brittleness nce; (7) Tom qab lub hnab ntim khoom ntim tau txias thiab muab tso rau, lub tshav kub sealing lub zog nce, thiab nws kuj yuav ua rau nkig. .

Countermeasures: (1) Raws li lub tshav kub sealing yam ntxwv ntawm cov khoom ntawm lub puab sealing txheej, xaiv qhov tsim nyog ua kub, siab thiab kub sealing lub sij hawm; (2) Txhim kho lub xeev saum npoo ntawm lub tshav kub sealing riam kom lub ntsej muag ntawm lub sealer du; Cov ntaub tetrafluoroethylene tau npog zoo; (4) Xaiv lub silicone roj hmab ncoo uas tsim nyog hardness.

3. Kuv yuav ua li cas yog tias lub hnab yog warped tom qab tshav kub sealing?

Yog vim li cas: (1) Lub thickness ntawm cov zaj duab xis composite yog inconsistent; (2) Thaum tshav kub kub sealing kub yog siab dhau los yog lub sij hawm kub sealing ntev dhau lawm; (3) Nyob rau hauv longitudinal tshav kub sealing riam ib feem, khiav khiav ntawm cov zaj duab xis composite tsis ncaj; (4) Cov cua txias tsis yog (5) Lub sijhawm kho tsis txaus; (6) Lub tshav kub tsis kam ntawm qhov chaw substrate zaj duab xis yog qhov tsis zoo; (7) Lub nro sib txuam tswj ntawm cov txheej txheem sib xyaw ua ke thaum lub sij hawm sib xyaw ua ke tsis raug tswj kom zoo, ua rau muaj kev ntxhov siab tom qab kho thiab kho, tshwj xeeb tshaj yog cov kev ua tsis tiav no feem ntau tshwm sim thaum cov zaj duab xis sib xyaw yog nyias.

Kev ntsuas qhov ntsuas: (1) Kho qhov nro ntawm cov menyuam ntab; (2) Xaiv lub puab sealing substrate nrog kub kub sealability; (3) Kho cov cua sov sealing kub kom haum rau qhov kub thiab txias; (4) Siab txias; (5) Siab loj; (6) Rov xaiv cov zaj duab xis saum npoo av;. (7) Kho qhov nro ntawm txhua feem ntawm cov khoom siv sib xyaw ua ke, thiab sim ua kom tus nqi thim rov qab ntawm ob qho kev sib xyaw ua ke sib npaug.

4. Kuv yuav ua li cas yog hais tias lub contour ntawm lub tshav kub sealing nto tsis meej? (Lub riam qauv tsis meej)

Yog vim li cas: (1) Lub sijhawm txias yog luv; (2) Lub phaj txias yog nyob rau hauv kev sib cuag tsis zoo; (3) Ntu ntug yog melted vim cua sov ntawm silicone ncoo; (4) Lub longitudinal tshav kub sealing quab yuam yog tsis sib npaug; (5) Lub ntug ntawm lub tshav kub sealing riam yog tsis zoo huv si thiab blunt.

Kev ntsuas ntsuas: (1) Kho lub sijhawm txias; (2) Kho lub phaj txias; (3) Hloov los yog kho lub tshav kub sealing riam; (4) Tiv thaiv ntug ntawm melting vim overheating ntawm silicone ncoo.

5. Kuv yuav ua li cas yog tias lub zog sealing tsis zoo?

Yog vim li cas: (1) Cov nplaum nyob rau hauv cov zaj duab xis composite tsis tau hardened txaus; (2) Cov cua sov sealing tej yam kev mob tsis tsim nyog; (3) Qhov kev ncua deb ntawm lub tshav kub sealing riam thiab txias riam yog ntev dhau lawm; (4) Muaj teeb meem nrog cov txheej txheem sealing sab hauv; (5) Tsis zoo thaum tshav kub kub-sealing tsis kam ntawm tus number case, ua rau txo qis hauv cov khoom sib xyaw ntawm cov yeeb yaj kiab ntawm qhov kub-sealed; (6) Plua plav, plua plav thiab lwm yam khoom siv ua raws li cov khoom siv hluav taws xob kaw; (7) Tsis tshua muaj zog sib xyaw lossis txo qis zog ntawm qhov kub-sau qhov ntau dhau.

Kev ntsuas ntsuas:

(1) Txhawb lub hardening (kho, kho) ntawm cov nplaum los ntawm thermal aging thiab txhim kho lub zog sib xyaw thiab cov cua sov ua haujlwm ntawm cov zaj duab xis sib xyaw.

(2) Xaiv qhov zoo tshaj plaws thaum tshav kub kub sealing tej yam kev mob (kub, lub sij hawm thiab siab) raws li muaj pes tsawg leeg ntawm cov zaj duab xis composite, tshav kub sealing xeev, thiab lwm yam, los yog txhim kho cov cua sov sealing txoj kev, thiab txias nws tam sim ntawd tom qab tshav kub sealing.

(3) Tshawb xyuas lub txee lub neej thiab kev cia khoom ntawm cov cua sov-sealing txheej zaj duab xis. Yog tias cov txheej txheem cua sov siv cov txheej txheem qub ntawm cov yeeb yaj kiab thiab cov yeeb yaj kiab thaum tshav kub kub, yuav tsum tau them nyiaj tshwj xeeb.

(4) Ua kom lub thickness ntawm lub tshav kub sealing txheej zaj duab xis.

(5) Hloov hom thiab qib ntawm cov cua sov-sealing txheej zaj duab xis, thiab siv cov txheej txheem sealing sab hauv nrog cov khoom tiv thaiv kev ua qias tuaj thaum tshav kub-sealing.

(6) Tshawb xyuas seb qib ntawm cov nplaum puas ua tau raws li qhov yuav tsum tau ua (qhov exudation ntawm cov khoom tsis muaj molecular hauv cov resin tej zaum yuav cuam tshuam rau cov khoom ntawm cov nplaum).

(7) Txhim kho qhov kev sib khi ntawm cov cua sov ua haujlwm ntawm cov txheej txheem kub sealing (substrate), tswj cov ntsiab lus ntawm tus neeg sawv cev, thiab siv mLLDPE zaj duab xis.

(8) Tswj cov ntsiab lus monomer ntawm MDI hauv cov nplaum sib xyaw.

(9) Tshawb xyuas qhov kev kho mob ntawm cov thermal cover.

(10) Hloov tus cwj mem (ob hom kua dej yog qhov zoo tshaj).

(11) Hloov cov qauv luam ntawv ntawm lub hnab ntim khoom kom cov ntawv luam tawm nrog tus number case tsis txhob muaj qhov kub-sealing, lossis hloov cov txheej txheem kub-sealing. (Kev saib xyuas tshwj xeeb yog them rau cov xim hlau tsis txhob muab luam tawm ntawm lub foob).
