Cov luv luv ntawm Quarter Fold Toilet Seat Cover

Ib lub hlis twg -fold lub rooj zaum tso quav tso quav (kev tsim khoom lag luam: QF-TSC) yog ib qho - siv cov khoom siv tu cev uas tsim los rau kev tsim khoom loj thiab xa mus rau hauv kev lag luam, pej xeem, thiab chaw ua haujlwm huv huv. Kev faib tawm raws li ISO 15715: 2001 (Cov khoom siv pov tseg rau kev nyiam huv) thiab ASTM D6866 (tus qauv biodegradability), nws yog tsim los txo cov ntoo khaub lig-kev sib kis ntawm qhov tseeb-folded, kua-cov qauv tiv thaiv tau sib xws nrog cov tshuab xa hluav taws xob.

Lub hauv paus substrate khoom ntawm lub quarter-fold lub rooj zaum lub rooj zaum muaj cov hauv qab no:

Cov khoom siv tseem ceeb: Virgin kraft pulp (GSM: 18–22 g / m²) los yog siv cov fiber ntau sib xyaw (tsawg kawg 60% tom qab- cov neeg siv khoom pov tseg, FSC- ntawv pov thawj xaiv tau) nrog rau Cobb 60-feeb dej nqus tus nqi tsawg dua lossis sib npaug li 30 g / m² (ib TAPPI)
Cov Txheej Txheem Txheej Txheem: Co-extruded polyethylene (PE) zaj duab xis (thickness: 8-12 μm) siv los ntawm extrusion lamination, nrog lub zog tev ntau dua lossis sib npaug li 0.3 N / 15 mm (ASTM D1876) los tiv thaiv delamination nyob rau hauv ntub dej.
Additives: Khoom noj khoom haus- qib cationic surfactants (0.05–0.1% los ntawm qhov hnyav) rau deg hydrophilicity; xaiv cov tshuaj tiv thaiv kab mob (xws li nyiaj ion, benzalkonium chloride) nrog cov cav txo qis dua lossis sib npaug rau 2 rau E. coli thiab S. aureus (ib ISO 22196).

Txoj Kev Tsim Khoom & Kev Tswj Xyuas Zoo rau Lub Plaub Hlis -Fold Toilet
Lub Rooj Zaum

- Cov kab ntau lawm

Kev npaj Pulp: Tshuag sib xws 3-5% cov khoom, ua kom zoo rau 30-35℃SR freeness (TAPPI T227).
Kev sib sau: Fourdrinier tshuab ceev 250-300 m / min, nrog lub tshuab nqus tsev dewatering (siab: 0.6-0.8 MPa) rau lub hauv paus hnyav.
Lamination: Extrusion kub 280-300 degree, nip siab 1.2-1.5 MPa, nrog kev kho mob corona (deg zog Ntau dua los yog sib npaug rau 38 dynes / cm) rau PE zaj duab xis adhesion.
Folding & Cutting: Automated rotary tuag-txiav (kev kam rau siab ± 0.3 mm) ua raws li servo-tsav folding, nrog 100% kev soj ntsuam pom qhov tsis xws luag (xws li kua muag, misfolds, zaj duab xis khoob).

- Cov Ntawv Pov Thawj Zoo

Batch Inspection: AQL 1.5 rau qhov tsis xws luag (ib ISO 2859-1); Yam tsawg kawg 3 random kuaj ib 10,000 units kuaj rau tensile lub zog, kua kuj, thiab biodegradability.
Sterility (Optional): Gamma irradiation (25–30 kGy) rau kev kho mob- qib sib txawv, nrog endotoxin qib tsawg dua lossis sib npaug li 0.5 EU/mL (ISO 10993-11).
