Chidule cha pulasitiki pansi

1. Mayina

Zambiri zodziwika bwino za pulasitiki pansi:

1) PVC: poly vinilu kloridi

2) LVT: matailosi apamwamba a vinyl

3) LVP: matabwa apamwamba a vinilu

4) Vinyl pansi

5) matabwa a vinyl

6) WPC: matabwa pulasitiki gulu

7) SPC: mwala pulasitiki gulu, Mayiko Occident amatcha mtundu uwu wa pansi RVP (rigid vinilu thabwa).

2. Gulu

Pakali pano, PVC pepala pansi amabwera mu mitundu iwiri ikuluikulu. Mtundu woyamba umakhala ndi zinthu zofananira zoyambira pansi mpaka pamwamba. Pakawonongeka pamtundu uliwonse monga kuwotcha kapena kukanda, zitha kubwezeretsedwa mosavuta kudzera mukupukutidwa ndi makina opera ndikugwiritsa ntchito sera. Mtundu wachiwiri umapangidwa ndi PVC yoyera yowonekera pamwamba, ndi gawo la pansi lomwe lili ndi gulu losindikizira ndi wosanjikiza wa thovu. Mwachiwonekere, mtundu woyamba umapereka maubwino ambiri pankhani ya kukhazikika ndi kukonza.

Pankhani ya mawonekedwe, mapepala a PVC amatha kugawidwa ngati ophimbidwa kapena mu mawonekedwe a pepala. Kuphatikiza apo, LVT ndi WPC zimagwera pansi pagulu lolimba la pulasitiki, pomwe SPC (RVP) imayimira mtundu wa pepala lolimba. Kuphatikiza apo, pansi pa PVC chitha kugawidwa kukhala wamba (Dry Back), loko (dinani), ndi osakhala guluu (Lose lay) kutengera njira za msonkhano.

Kusinthasintha komanso kusiyanasiyana kwamakampani opanga mapepala a PVC kumapereka mayankho osiyanasiyana ogwiritsira ntchito. Kaya ndizosavuta kukonza, kulimba, kapena zofunikira zinazake zapagulu, pali zosankha zingapo zomwe zingakwaniritse zosowa zosiyanasiyana. Pamene ukadaulo ukupitilirabe patsogolo, luso ndi chitukuko cha mapepala a PVC atha kubweretsanso zina zambiri m'tsogolomu.

3. Mapangidwe

ndi

Pulasitiki pansi amapangidwa ndi wosanjikiza kumbuyo, core layer, glass fiber, mapepala okongoletsera ndi kuvala wosanjikiza kuchokera pansi mpaka pamwamba.

4. Mlozera wazinthu zazikulu

• Kukhazikika: The shrinkage ndi kukula kwa mankhwala: 80 ℃, 6 hours. 0.25%, 0.15%

• Kutentha buckling: 80 ℃ maola 6 EN

• Kukoka mphamvu ya loko: Kutentha kwanthawi zonse (23℃): 5.0mm>13-15kgs/5cm, 4.2mm>12kgs/5cm; M'mphepete mwachidule gwiritsani loko loko yooneka ngati V: 4.2mm>15-18kgs/5cm.

• Mphamvu ya peeling: Mphamvu yomatira ya filimu yamtundu ndi zapakati. • Kuwala:10+/-2.
