Lub ntiaj teb ntawm kev ntim khoom tau tsim sai heev nyob rau xyoo tas los no, nrog rau kev siv cov khoom siv siab heev rau kev ntim khoom. Ntawm cov ntaub ntawv no, PP woven hnab tau dhau los ua neeg nyiam vim lawv cov kav ntev, ntau yam, thiab siv tau zoo. Cov hnab no feem ntau siv rau ntim ntau yam khoom, nrog rau cov hnab calcium carbonate, hnab cement, thiab hnab gypsum.

PP woven hnab yog tsim los ntawm polypropylene, uas yog ib tug thermoplastic polymer siv rau ntau yam kev siv. Cov khoom siv no yog ruaj, hnav, thiab tiv taus cov dej noo, uas ua rau nws zoo tagnrho rau ntim cov khoom uas yuav tsum tau muaj kev tiv thaiv los ntawm ib puag ncig sab nraud. PP woven hnab kuj hloov tau, uas tso cai rau lawv siv rau ntau yam ntawm cov khoom sib txawv thiab ntau thiab tsawg.

Ib qho ntawm feem ntau siv PP woven hnab yog rau ntim calcium carbonate, uas yog siv los ua ib tug muab tub lim nyob rau hauv ntau yam khoom, xws li xim, ntawv, thiab yas. Cov hnab ntim khoom siv calcium carbonate yog tsim los kom tuab thiab muaj zog, vim tias cov khoom no hnyav thiab yuav tsum muaj lub hnab ruaj khov rau kev thauj mus los thiab khaws cia.

Lwm qhov kev siv PP woven hnab yog rau ntim cov cement, uas yog ib qho ntawm cov khoom siv dav siv hauv ntiaj teb. Cov hnab cement feem ntau yog tsim los ntawm kev sib xyaw ntawm PP woven npuag thiab kraft ntawv, uas muab kev ruaj khov thiab tiv thaiv kev ya raws. Cov hnab no muaj nyob rau hauv ntau qhov sib txawv, xws li cov hnab me me rau DIY tej yaam num mus rau lub hnab loj rau kev lag luam kev tsim kho.

PP woven hnab kuj feem ntau siv rau ntim gypsum, uas yog ib tug mos sulfate ntxhia siv nyob rau hauv drywall thiab plaster khoom. Gypsum hnab yog tsim los ua lub teeb yuag thiab yooj yim los tuav, vim lawv feem ntau siv hauv cov chaw tsim kho uas cov neeg ua haujlwm yuav tsum tau txav cov ntaub ntawv ntau sai thiab ua tau zoo. Cov hnab no kuj tseem ruaj khov, uas ua kom ntseeg tau tias gypsum tiv thaiv los ntawm ib puag ncig sab nraud thiab tseem nyob ruaj khov thaum thauj thiab khaws cia.

Hauv kev xaus, PP woven hnab yog ib qho tseem ceeb thiab ntau yam khoom siv hauv kev lag luam ntim. Lawv cov kav ntev, yoog raws, thiab cov nqi tsim nyog ua rau lawv muaj kev xaiv zoo rau ntim ntau yam khoom, suav nrog cov hnab calcium carbonate, hnab cement, thiab hnab gypsum. Txoj kev loj hlob ntawm cov ntaub ntawv siab heev thiab cov txheej txheem tsim tshiab yuav txuas ntxiv txhim kho kev ua tau zoo thiab ntau yam ntawm PP woven hnab, ua rau lawv yog ib feem tseem ceeb ntawm kev lag luam ntim niaj hnub.
