Nyeem rau kom tiav, cov ntaub ntawv - rov qab tshawb xyuas ntawm SPC flooring thickness.

1. Nkag siab SPC Flooring Structure thiab Thickness Composition

Yuav kom nkag siab seb qhov tuab cuam tshuam li cas rau kev ua haujlwm, ib tus yuav tsum xub nkag siab txog cov txheej txheem txheej txheem ntawm SPC plank. Ib tug qauvSPC yas flooringplank muaj plaub txheej ua haujlwm, txhua qhov ua rau muaj kev ua haujlwm tshwj xeeb:

• UV Txheej (Hnub Txheej)- Lub pob tshab, UV- kho tau cov coated topcoat, feem ntau yog 0.3–0.5mm tuab, muab khawb, stain, thiab puas. Cov txheej no tsis cuam tshuam rau tag nrho cov plank thickness.
• Kho kom zoo nkauj zaj duab xis txheej- Lub siab- daws teeb meem luam tawm yas zaj duab xis (0.07–0.12mm) uas rov ua cov ntoo lis, pob zeb zoo nkauj, lossis cov qauv paub daws teeb nrog cov duab fidelity.
• SPC Core Txheej (Ntxig Core)- Cov pob txha pob txha, extruded los ntawm kev sib xyaw ntawm ntuj limestone hmoov (calcium carbonate), polyvinyl chloride resin, thiab stabilizing agents. Cov txheej no suav rau80-90% ntawm tag nrho cov plank thicknessthiab yog tus thawj txiav txim ntawm rigidity, seem stability, thiab compressive zog.
• Txuas Underlayment Pad- Ib txheej ua ntej- khi cushioning txheej, feem ntau ua los ntawm IXPE (Irradiation Hla- txuas Polyethylene), EVA (Ethylene-Vinyl Acetate), los yog cork, xws li 1.0mm txog 3.0mm. Nws muab acoustic dampening, me me subfloor kho, thiab thermal rwb thaiv tsev.

Feem ntau tag nrho cov thickness specifications ntawm lub khw muaj xws li4mm, 5mm, 6mm, 7mm, thiab 8mm. Hauv cov khoom hnyav -kev lag luam thiab kev lag luam, 10mm thiab 12mm cov khoom kuj muaj. SPC core txheej feem ntau yog 3.0-5.5 hli ntawm tag nrho, nrog rau cov ntaub qhwv txuas ntxiv rau qhov seem. Kev nkag siab txog qhov kev tawg no yog qhov tseem ceeb vim tias ob yam khoom uas tau sau tias "6mm" tuaj yeem ua tau txawv heev yog tias ib qho faib 4.5mm rau hauv cov tub ntxhais thiab 1.5mm rau lub ncoo tiv thaiv 4.0mm core nrog 2.0mm ncoo.

2. Qhov Thickness cuam tshuam li cas rau Core Performance Metrics

2.1 Stability thiab Deformation Resistance

SPC core txheej yog lub hauv paus txheej txheem tswj hwm hauv pem teb tiv thaiv thermal expansion, contraction, thiab substrate-induced deformation. Cov tub ntxhais tuab (Ntau dua lossis sib npaug rau 4.0mm SPC txheej, sib haum rau Ntau dua lossis sib npaug rau 6mm tag nrho cov tuab) tsim cov qauv nruj dua nrog covqis linear thermal expansion coefficient. Hauv cov ntsiab lus siv tau, qhov no txhais tau tias SPC flooring ntawm 6 hli thiab siab dua tuaj yeem ntsia tau ntev, tsis muaj kev cuam tshuam - xws li qhib - thaj chaw nyob, txoj kev hauv tsev siab tshaj 12 meters, lossis kev lag luam chaw tos txais - nrog kev pheej hmoo ntawm peaking, gapping, los yog kawg - sib sib cais.

By contrast, 4mm-thin SPC planks place extreme demands on subfloor flatness. Even minor substrate undulations (deviations >2 hli dhau ntawm 2-meter ncua) tuaj yeem tsim thaj chaw flex. Nyob rau hauv kev rov qab taug kev taw, cov kev txav me me no ua rau "nias" lub suab, xauv lub cev qaug zog, thiab qhov tshwm sim ntawm cov pob txha tawg. Rau cov chav uas muaj cua sov hauv qab lossis hauv cov huab cua uas muaj qhov hloov pauv ntawm lub caij ntuj sov,6mm yam tsawg kawg nkaus thickness yog pom zootxhawm rau xyuas kom muaj kev ncaj ncees nyob rau hauv pem teb kev pab cuam lub neej.
