Hauv tsab ntawv blog no, peb tshawb nrhiav qhov khawv koob ntawm PP nonwovens thiab kawm vim li cas nws tau dhau los ua qhov kev daws teeb meem rau ntau tus neeg tsim khoom thiab cov neeg siv khoom.
PP tsis yog woven ntaub yog dab tsi?
PP cov ntaub tsis yog woven Cov ntaub no yog ua los ntawm cov thermoplastic polymer polypropylene siv cov txheej txheem tshwj xeeb hu ua spunbond lossis meltblown. Cov txheej txheem no suav nrog kev rho tawm cov polymer fibers molten, uas tom qab ntawd sib txuas ua ke los ua cov qauv zoo li ntaub. Cov ntaub uas tshwm sim muaj lub zog zoo kawg nkaus, ruaj khov thiab tiv taus dej noo, ua rau nws haum rau ntau yam kev siv.
Cov ntawv thov hauv Kev Kho Mob:
Ib qho ntawm cov chaw uas PP nonwovens ci ntsa iab yog nyob rau hauv kev lag luam kev kho mob. Nws cov yam ntxwv zoo heev ua rau nws zoo tagnrho rau kev siv rau hauv cov khaub ncaws kho mob, lub ntsej muag thiab lwm yam khaub ncaws tiv thaiv. Lub peev xwm ntawm cov ntaub los tiv thaiv cov kua thiab cov khoom me me pab tswj kom muaj ib puag ncig huv si thiab tiv thaiv cov neeg mob thiab cov kws kho mob. Tsis tas li ntawd, nws qhov ua pa tau ua kom muaj kev nplij siab rau lub sijhawm ntev ntawm kev siv, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov tsev kho mob, chaw kho mob thiab txawm tias cov chaw kho mob hauv tsev.
Kev siv ua liaj ua teb:
Cov ntaub PP nonwovens kuj muaj qhov chaw hauv kev ua liaj ua teb, hloov pauv txoj kev cog qoob loo. Nws qhov permeability tso cai rau dej thiab cov as-ham kom ncav cuag cov hauv paus hniav thaum tiv thaiv cov nroj tsuag loj hlob. Cov ntaub no siv dav ua cov ntaub npog av, cov ntaub npog qoob loo, thiab txawm tias hauv cov kab ke ua teb ntsug. Nws qhov xwm txheej sib dua ua rau nws yooj yim rau kev tuav thaum muab cov khoom thaiv zoo tiv thaiv huab cua hnyav, ua kom ntseeg tau tias cov qoob loo zoo.
Kev lag luam zam:
Cov lag luam zam kuj tau hnov qhov zoo nkauj ntawm PP cov ntaub tsis-woven. Cov neeg tsim qauv thiab cov kws ua tes ua haujlwm txaus siab rau nws qhov kev ua tau zoo thiab yooj yim ntawm kev tuav, tso cai rau lawv tsim cov khaub ncaws tshwj xeeb thiab tshiab. Cov ntaub tuaj yeem zas xim, luam tawm, thiab txawm tias pwm rau hauv cov duab xav tau, ua rau muaj kev muaj tswv yim tsis muaj kev txwv. Ntau thiab ntau lub tuam txhab tab tom suav nrog PP nonwovens rau hauv lawv cov khoom lag luam vim lawv txoj kev phooj ywg ib puag ncig, kev siv rov qab, thiab muaj peev xwm hloov pauv mus rau hauv kev zam ruaj khov.
Kev nce qib ntawm lub tsheb:
Hauv kev lag luam tsheb, PP nonwovens tau ua pov thawj tias yog cov khoom hloov pauv loj. Nws siv dav hauv cov khoom siv sab hauv tsheb xws li lub rooj zaum, lub taub hau tsheb, lub qhov rooj thiab lub hnab hauv qab tsheb. Nws qhov ruaj khov, tiv taus UV hluav taws xob thiab yooj yim txij nkawm pab txhawb rau qhov zoo nkauj thiab lub neej ntev ntawm lub tsheb. Tsis tas li ntawd, nws cov khoom sib dua pab txhim kho kev siv roj, ua rau nws yog qhov kev xaiv zoo rau cov chaw tsim khoom thiab cov neeg siv khoom uas xav txog ib puag ncig.
xaus lus:
Kev siv dav dav ntawmPP cov ntaub tsis yog wovenHauv ntau qhov chaw ua pov thawj nws qhov zoo thiab kev hloov pauv tau zoo heev. Txij li kev kho mob mus rau kev ua liaj ua teb, zam thiab tsheb, cov khoom siv no txuas ntxiv hloov pauv kev lag luam nrog nws qhov ruaj khov, kev hloov pauv tau yooj yim thiab kev phooj ywg ib puag ncig. Thaum thev naus laus zis thiab kev tsim kho tshiab nce qib, peb tos ntsoov yuav pom ntau daim ntawv thov zoo siab rau PP nonwovens, tsim cov cib fim tshiab thiab tsav tsheb kev txhim kho kom ruaj khov.
Yog li, txawm tias koj nyiam qhov xis nyob ntawm cov khaub ncaws kho mob uas tsis yog woven lossis txaus siab rau cov kev tsim kho tshiab tshiab, siv sijhawm me ntsis los txaus siab rau seb PP nonwovens haum rau peb lub neej txhua hnub li cas.
