Qhia ntawm PP yaj tshuab cov ntuag cov ntaub

Mown blown daim ntaub (yaj lub tshuab tsis-woven npuag) yog cov khoom lag luam ua los ntawm cov ntaub ntawv siab yaj siab PP (polypropylene) sib xyaw xim tsis muaj ntaub. Nws yog cov khoom siv tseem ceeb ntawm daim npog ntsej muag. Qhov txoj kab uas hla ntawm spinneret fiber ntau tuaj yeem ncav cuag 0.001 txog 0.005 hli. Muaj ntau lub voids, fluffy qauv, zoo wrinkle tsis kam, thiab cov cim capillary. Cov ntsej muag fiber ntau ua rau kom muaj pes tsawg thiab thaj tsam ntawm cov roj hauv ib cheeb tsam, kom cov ntaub meltblown muaj cov dej tsis zoo, kev tiv thaiv, tiv thaiv kub thiab nqus roj. Cov. Nws lub ntsiab siv suav nrog huab cua pom, kua qaub-ua kua pom kev lim, ua kom huv cov zaub mov tu cev, muaj cov hmoov av hmoov av tsim ntau lawm, thiab lwm yam. nqus cov ntaub ntawv, cov roj teeb hluav taws xob cais, thiab cov tawv qog pleev ntsej muag. thiab ntau ntxiv. Txij li thaum lub ntiaj teb tawm ntawm cov kab mob yas tshiab thoob ntiaj teb, Tsoom Fwv Saib Xyuas Cov Khoom Siv thiab Cov Thawj Coj ntawm Lub Xeev Pawg Neeg Saib Xyuas Kev Tshawb Fawb tau thov cov tuam txhab muaj feem cuam tshuam rau kev tsim kho cov kab ntau lawm, muab tso rau hauv kev tsim tawm sai li sai tau, thiab nthuav cov khoom ntawm meltblown nonwovens hauv kev ua lag luam muab kev tiv thaiv rau kev tiv thaiv thiab tswj tus kabmob sib kis.

Ntau qhov chaw thov ntawm meltblown tsis-woven ntaub:
1. Daim ntawv thov hauv thaj chaw ntawm huab cua lim: siv rau hauv cov cua lim, ua lub tshuab ua kom muaj cua lim, thiab siv rau kev ntxhib ntxoo thiab nruab nrab kev ua haujlwm ntawm huab cua nrog cov dej ntws loj dua. Nws muaj qhov zoo ntawm cov tsis kam, siab zog, zoo tshaj acid thiab alkali tsis kam, corrosion tsis kam, ruaj khov efficiency, kev pab lub neej ntev, thiab tus nqi qis.
2. Application in the medical and health field: The dust-proof port made of melt-blown cloth has low breathing resistance, is not stuffy, and has a dust-proof efficiency of up to 99%. It is widely used in hospitals, food processing, mines, etc. that require dust and bacteria prevention In the workplace, the anti-inflammatory and analgesic film made by the product after special treatment has good air permeability, no toxic side effects, and easy to use. SMS products compounded with spunbond fabrics are widely used in the production of surgical clothing and other sanitary products. <br>
3. Cov khoom siv ua kua roj lim thiab roj teeb roj: Polypropylene yaj cov tshuab pliav yog siv los lim cov kua qaub thiab kua roj, roj, thiab lwm yam. Nws muaj cov kev ua tau zoo heev, tau raug suav hais tias yog qhov khoom siv zoo diaphragm los ntawm kev lag luam roj teeb hauv tsev thiab txawv teb chaws, thiab tau siv dav dav, Tsis tsuas yog txo tus nqi roj teeb, ua haujlwm tsis yooj yim, thiab txo tau ntau qhov nyhav thiab ntim ntawm lub roj teeb.
4. Cov ntaub ntawv roj-cov khoom siv thiab cov ntaub so roj: muaj ntau cov roj-cov ntaub ntawv ua los ntawm polypropylene meltblown daim ntaub, uas tuaj yeem nqus cov roj txog 14-15 zaug lawv tus kheej qhov hnyav, tau siv dav hauv cov txheej txheem tiv thaiv ib puag ncig thiab cov dej-sib cais cov haujlwm. Tsis tas li ntawd, lawv tau siv rau hauv kev lag luam kev lag luam. , Yuav siv tau cov ntaub ntawv huv rau roj thiab hmoov av. Cov ntawv thov no muab tag nrho kev ua si rau tus yam ntxwv ntawm polypropylene nws tus kheej thiab cov adsorption ntawm ultrafine fibers ua los ntawm meltblown.
5. Cov ntaub thaiv hluav taws xob cua sov: qhov nruab nrab ntawm cov xov meltblown fiber ntau li ntawm 0.5-5μm, thiab lawv tau ncaj qha rau cov ntaub qhwv tsis ua haujlwm los ntawm kev nteg random. Yog li ntawd, qhov tshwj xeeb nplaim thaj chaw ntawm meltblown fibers yog qhov loj thiab porosity yog qhov siab. Cov huab cua ntau tau khaws cia hauv cov qauv no. , Muaj peev xwm tiv thaiv kom tsis txhob muaj cua sov, yog kev lim tau zoo tshaj plaws thiab rwb thaiv tsev ntaub. Nws yog dav siv hauv kev tsim khaub ncaws thiab ntau yam khoom siv rwb thaiv tsev thermal. Xws li cov tawv tsho, cov tsho thom khwm, cov khaub ncaws ua pov thawj, paj rwb ntaub, thiab lwm yam, nws muaj qhov zoo ntawm lub teeb yuag, sov, tsis muaj dej noo noo, huab cua zoo permeability, thiab tsis muaj mildew.
