Polyurethane (PU), polyvinyl chloride (PVC), thiab PA micro-fiber composite yog peb lub hauv paus kev xaiv rau cov khau sab saud, rooj tog zaum muag muag, thiab tier-1 automotive tha xim sab hauv. Kev xaiv cov khoom nyob ntawm seb muaj pes tsawg tus neeg kho tshuab qhov pib, kev txwv kev ua raws cai, thiab kev tsim khoom-pem teb yield kev ua tau zoo. Cov pab pawg yuav khoom yuav tsum kaw qhov kev xeem-daim ntawv tshaj tawm-rov qab tsis hloov pauv cov lus piav qhia kev lag luam kom txo qis kev ua haujlwm tsis ua haujlwm thiab tom qab xa khoom rov ua haujlwm.
Tsab ntawv xov xwm no tshaj tawm ib sab-los-sab-sab kuaj-tsim kev ntsuas cov tshuab ntsuas, cov ntsiab lus tsis zoo ntawm cov khoom siv, thiab daim ntawv thov tshwj xeeb txiav txim siab ciam teb rau cov neeg yuav khoom ntau.
Core Mechanical Performance Benchmark
| Khoom | PU tawv (Nyob rau hauv qhuav) | PVC tawv (Calendered) |
|---|---|---|
| Hom Polymer | Polyurethane (polyester lossis polyether) | Polyvinyl chloride + plasticizers (30-40 phr) |
| Txheej txheej txheej | Cov kuab tshuaj los yog dej, thim rov qab- lub tsho tiv no | Calendering los yog kis txheej |
| Cov ntsiab lus ntawm plasticizer | 0% (yuav hloov tau) | 25-40% (DINP, DOTP, lossis DEHP zam) |
| Nto finish range | 680+ emboss qauv, siab -gloss rau matte | 380+ cov qauv, txwv cov ntsiab lus zoo |
| Qhov ceev (g / cm³) | 0.9–1.1 | 1.2–1.4 |
| Kev nqus dej (24h,%) | 5-10% (polyester puag) | 0.5–1.5% |
| Hydrolysis tsis kam | Polyether PU: zoo; polyester PU: tsis zoo nyob rau hauv high humidity | Zoo heev (tsis muaj ester txuas) |
Structure implicit rau khau sib dhos:PU tawv plasticizer-dawb muaj pes tsawg leeg txhais tau tias tsis muaj kev tsiv teb tsaws mus rau hauv cov khau hauv ob sab phlu lossis stitching. PVC tawv yuav tsum tau qis -migration plasticizers (DOTP lossis DINP) kom tsis txhob muaj roj av exudation- qhia qhov no hauv koj daim ntawv xaj-1.

Kev sib piv: Flex Resistance thiab Breathability
1 Flex Resistance (ISO 5402, 23 degree, 50 mm mandrel)
Rau khau ntaub vamp daim ntaub ntawv uas yuav tsum tau yam tsawg kawg nkaus 120,000 cycles, PU ua tiav 150,000 cycles los yog ntau tshaj yam tsis muaj cracking, thaum PVC ua tsis tau tejyam ntawm 80,000 thiab 100,000 cycles nrog zuj zus cracking ntawm flex kab. Rau kev nyab xeeb khau raj shafts xav tau 80,000 cycles, PU mus txog 120,000 cycles lossis ntau dua, thaum PVC ua tiav 90,000 cycles lossis ntau dua- txais tau rau qhov qis dua - daim ntawv thov kev ntxhov siab. Heel txee npog yuav tsum tau 60,000 cycles; PU xa 100,000 cycles lossis ntau dua piv rau PVC 70,000 cycles. ntiv taw cap hauv ob sab phlu yuav tsum tau 50,000 cycles; PU ua tiav 80,000 cycles lossis ntau dua piv rau PVC 60,000 cycles.
Engineering khoom:Rau cov khau kis las uas xav tau 120,000 flex cycles lossis ntau dua yam tsis muaj xim dawb, PU yog tib txoj kev xaiv. PVC ua tsis tau zoo los ntawm kev tawg tawg tshwm sim ntawm txoj kab flex.
2 Breathability thiab Moisture Management
| Parameter | Txoj Kev Xeem | PU (1.0 hli, microporous) | PVC (1.0 hli) |
|---|---|---|---|
| Dej vapor permeability (mg / cm²·h) | ISO 20344 Ntu 6.6 | 1.8–2.5 | 0.2–0.4 |
| Kev nqus dej noo (%, 4h) | ASTM D 570 Cov Lus Qhia Tshwj Xeeb | 4–8% | 0.5–1.0% |
| Cov dej nkag mus (kPa) | TS EN ISO 1420 | 30-50 (qib dej tsis zoo) | 80-120 (hauv qab) |
| Huab cua permeability (mm / s) | ASTM D 737 Cov | 0.5–2.0 | <0.1 |
Kev cuam tshuam rau khau khau:PU txo qis hauv - khau microclimate av noo los ntawm 30-40% piv rau PVC, txo cov kab mob hlwv. Rau cov khau khiab tsis muaj dej, PVC lub impermeability yog qhov zoo tab sis yuav tsum tau muaj dej noo- cov ntaub ntawv wicking.
3 Ntev thiab Kev Laus (Kev Ntsuas Ceev)
Thaum tshav kub kub aging ntawm 70℃rau 7 hnub qhia tensile tuav ntawm 60-70% polyester PU, 75-85% rau polyether PU, thiab 90-95% rau PVC nrog DOTP plasticizer. Kev ntsuas hydrolysis ntawm 70℃thiab 95% RH rau 7 hnub qhia tau tias tensile poob ntawm 40-50% rau polyester PU, 10-15% rau polyether PU, thiab qis dua 5% rau PVC. UV raug nyob rau hauv QUV 340 nm rau 300 teev qhia Delta E ntawm 2.5–4.0 rau polyester PU, 2.0–3.0 rau polyether PU, thiab 3.0–5.0 nrog nto chalking rau PVC. Txias tawg ntawm -20℃qhia tias tsis muaj kab nrib pleb rau ob hom PU, thaum PVC ua tsis tiav ntawm -15 degree.
Txoj cai xaiv qhov tseem ceeb:Rau cov huab cua sov lossis siab -cov av noo cia (xws li, Southeast Asia), qhia polyether-raws li PU lossis PVC. Polyester PU tensile zog poob qis dua 80 N / 15mm hauv 12 lub hlis ntawm 80% RH.
Tus nqi Optimization rau khau Factories
Tus nqi ntawm cov khoom siv ncaj qha tsuas yog 60 txog 70 feem pua ntawm tag nrho cov khoom siv sab saud. Kev txiav tawm tawm, kev siv nplaum, thiab kev tsis lees paub yuav tsum suav nrog hauv cov nqi suav tag nrho.
| Tus nqi Parameter | PU tawv (0.8mm) | PVC tawv (0.8mm) |
|---|---|---|
| Tus nqi khoom ib m² (FOB Tuam Tshoj, Ntau tshaj lossis sib npaug rau 5,000 m²) | $4.00–6.00 | $2.00–3.00 |
| Sab saum toj ib lub khau (m²) - khau ntaub, loj 9 US | 1.2 | 1.2 |
| Raw khoom nqi ib khub | $4.80–7.20 | $2.40–3.60 |
| Txiav yield (computerized tuag) | 84–88% | 79-84% (ntug curl + waviness) |
| Thaj chaw zoo rau ib khub (m²) | 1.36–1.43 | 1.43–1.52 |
| Cov khoom siv tau zoo raug nqi ib khub | $5.44–8.18 | $2.86–4.56 |
| Adhesive nqi ib khub | $0.18–0.25 (dej-raws li PU) | $0.28–0.38 (kua qaub + primer) |
| Kev ua haujlwm ncaj qha rau ib khub (ntev + stitching) | $0.35–0.50 | $0.55–0.75 |
| Tag nrho cov khoom siv sab saud + ua haujlwm ib khub | $5.97–8.93 | $3.69–5.69 |
| Factory rejection tus nqi (cracking / delamination) | 2.0–3.5% | 6.0–9.0% |
| Net nqi suav nrog kev tsis lees paub ib khub | $6.09–9.24 | $3.91–6.20 |
Txuag rau ib khub nrog PVC:$2.18–3.04 (36–49% qis). Rau 500,000 khub / xyoo, cov nyiaj khaws cia txhua xyoo tshaj **$ 1 lab **.
Tus nqi ntxiv:PVC qhov qis elongation (15-25% vs. PU's 40-60%) txo lub sij hawm mus sij hawm ntev los ntawm 8-12%, tab sis PVC's 20-30% ntau dua density nce nqi thauj khoom ib m². Cov nqi zais PU suav nrog cov kuab tshuaj rov qab rau DMF ntes ntawm $ 0.08–0.12 / m², tus nqi them nqi dej ntawm $ 0.30–0.50 / m², thiab ntim khoom tiv thaiv hydrolysis ntawm $ 0.02 / m² rau cov khoom xa tuaj tauj.
Tus nqi optimization pom zoo:Rau siab - nkawm khau (sneakers, khau seev cev), them tus nqi PU-PVC yuav ua tsis tau raws li qhov lav. Rau cov khau ua haujlwm lossis khau xws li khau nrog qhov chaw qis qis (shafts, straps), PVC muab kev ua tau zoo ntawm tus nqi qis dua.
