Cov kua nplaum ib txwm ua tsis tau thaum ntub.
Qhov ntawd yog qhov tseeb. Lawv poob lawv lub zog. Cores tawg. Txheej cais. Peb lub zog ntub dej nplaum sib txawv. Nws ua kom muaj kev sib raug zoo txawm tias tom qab nqus dej. Nws yog tsim rau pad core seams, tau cov khaubncaws sab nraud povtseg, thiab diaper core fixing. Peb tsim cov kua nplaum no los ntawm hauv av nrog lub zog ntub hauv siab. Peb ntxiv cov tshuaj tiv thaiv-hydrolysis thiab kua dej- tiv taus cov yam ntxwv ntawm qib molecular. Ntau tus neeg siv khoom nug peb, "Kuv yuav ua li cas thiaj li tiv thaiv kuv lub hauv paus kom tsis txhob poob thaum ntub?" Qhov no yog lo lus teb.
Peb siv SIS/SBS nrog polyolefin.
SIS/SBS sib xyaw ua kom zoo pib tack. Polyolefin muab lub zog ntxiv. Thaum ntub, cov saw hlau molecular rearrange. Lawv tsim ib lub cev muaj zog network. Ua haujlwm kub yog 140-160 degree. Ntawm 150 degree, yaj viscosity yog 3000-5000 mPa·s. Qhov ntawd ua kom ceev ceev ntawm cov ntaub ntawv ntxeem tau xws li fluff pulp, SAP qhwv, thiab cov ntaub so ntswg. Lub softening point yog 85-95 degree. Nyob ruaj khov ntawm lub cev kub. Tsis muaj dej ntws. Tsis muaj roj to.
Ntawm no yog cov ntaub ntawv ntub dej.
Hauv qhov thib peb -kev kuaj sim tom qab 24 teev hauv cov kua dej simulated, ntub lub zog tuav yog tshaj 75%. Cov txheej txheem zoo li qub yog nyob ntawm 30-40%.

Lub hauv paus tseem nyob twj ywm thaum ntub tag nrho. Tsis tawg. Tsis poob. Tsis muaj clumping. Tsawg tsiv teb tsaws. SAP absorbency poob qis dua 5%. Peb muab peb lub tshuab. SIS-raws li rau siab tack thiab softness. SBS- sib tov kom muaj zog dua ntub thiab kub ua hauj. Polyolefin PO rau cov ntxhiab tsw thiab tsis tshua muaj khaus. Qhov ntawd yog peb lub zog Wet Strength Adhesive.
