Nyob rau hauv xyoo tas los no, tarpaulins, uas yog ib qho tseem ceeb hloov tau yooj yim tiv thaiv thiab npog cov ntaub ntawv, tau tuav ruaj khov xav tau thoob ntiaj teb, nrog rau kev lag luam loj txuas ntxiv nthuav dav thiab daim ntawv thov thaj chaw txuas ntxiv mus. Tsav los ntawm ntau yam xws li kev tsim kho vaj tse, kev thauj mus los thiab kev thauj mus los, kev tiv thaiv kev ua liaj ua teb, kev ua si sab nraum zoov, thiab cov lus teb thaum muaj xwm txheej ceev, kev lag luam tarpaulin tau tsim cov txheej txheem tsim khoom thiab cov khoom siv tiav, nthuav tawm cov yam ntxwv sib txawv hauv cov qauv hauv cheeb tsam, cov qauv khoom, thiab qib thev naus laus zis.
Los ntawm cov khoom siv sab nrauv, cov tuam txhab tarpaulin feem ntau yog tsom rau hauv cheeb tsam nrog kev lag luam textile thiab tshuaj lom neeg, tsim cov khoom lag luam feem ntau raws li kev ua cov khoom siv raw, cov ntaub npuag, txheej, thiab cov khoom tiav. Cov tuam txhab loj, siv lawv cov khoom loj- nplai ntau lawm thiab cov khoom siv thev naus laus zis, tuaj yeem muab cov khoom lag luam nrog ntau yam kev qhia tshwj xeeb thiab qib kev ua tau zoo, suav nrog ntau theem ntawm kev xav tau los ntawm qis-kawg ua liaj ua teb npog rau siab- kawg kev tiv thaiv kev lag luam; me thiab nruab nrab- cov tuam txhab loj feem ntau paub txog lawv cov kev pabcuam sib txawv thiab kev pabcuam, ua tau raws li cov kev cai tshwj xeeb ntawm cov neeg siv khoom hauv cheeb tsam hais txog qhov loj me, kev ua haujlwm, thiab tus nqi. Nyob rau hauv cov nqe lus ntawm kev tsim cov txheej txheem, lub peev xwm los tswj cov txheej uniformity, composite zog, thiab huab cua kuj tau dhau los ua ib qho tseem ceeb qhia rau kev ntsuas cov khoom zoo, tsav kev txhim kho tsis tu ncua ntawm tag nrho cov thev naus laus zis theem ntawm kev lag luam.
Nyob rau hauv cov nqe lus ntawm kev thov qauv, ib txwm sectors tseem dominate. Kev tsim kho kev lag luam siv ntau npaum li cas ntawm tarpaulin rau qhov chaw ib ntus thiab cov ntaub ntawv npog; kev lag luam kev thauj mus los thiab kev thauj mus los tso siab rau cov dej tsis zoo thiab puas tsuaj -cov ntaub ntawv tiv thaiv kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom thaum lub sijhawm thauj mus los ntev -; thiab kev ua liaj ua teb dav siv lub teeb yuag thiab ruaj khov polyethylene-coated tarpaulins rau cov qoob loo npog thiab tiv thaiv nag thiab Frost. Lub caij no, txoj kev loj hlob sai ntawm cov xwm txheej tshwm sim xws li kev ua si sab nraum zoov, kev ua kis las, cov chaw ua yeeb yam ib ntus, thiab kev pab cuam thaum muaj xwm txheej ceev tau ua rau muaj kev xav tau siab - lub zog, lub teeb yuag, thiab yooj yim- rau- nruab tarpaulins, tsav tsheb sib koom ua lag luam ntawm cov khoom siab - kawg.
Hauv kev lag luam hauv cheeb tsam, Asia - cheeb tsam Pacific, vim muaj kev nqis peev hauv kev lag luam thiab cov txiaj ntsig ntawm kev tsim khoom, tau dhau los ua lub ntiaj teb loj tshaj plaws tarpaulin ntau lawm thiab noj cheeb tsam; European thiab Asmeskas kev lag luam muaj cov kev xav tau siab dua rau kev tiv thaiv ib puag ncig thiab cov nplaim hluav taws kub hnyiab, ua rau cov tuam txhab hauv zos kom nrawm rau kev tshawb fawb thiab kev tsim cov khoom ntsuab thiab cov khoom siv; Cov teb chaws lag luam tawm tshiab, nrog kev txhim kho kev lag luam thiab kev paub txog kev tiv thaiv kev puas tsuaj ntau ntxiv, tau pom qhov kev xav tau loj hlob thiab muaj kev vam khom siab.
Hais txog tus nqi, kev lag luam tarpaulin muaj kev hloov pauv raws sijhawm vim cov khoom siv raw khoom hloov pauv, cov nqi hluav taws xob, thiab kev nqis peev ib puag ncig, tab sis tag nrho cov qauv yog mus rau kev ruaj ntseg. Cov neeg siv tau nce siab rau tus nqi-kev ua tau zoo thiab tag nrho lub neej- tus nqi voj voog thaum yuav khoom, ua rau cov tuam txhab ua kom zoo dua cov qauv thiab cov txheej txheem kom ua tiav qhov sib npaug ntawm kev ua tau zoo thiab tus nqi. Hauv cov ntsiab lus, kev lag luam tarpaulin tam sim no yog tus cwj pwm los ntawm ntau qhov kev thov, cov khoom siv stratified, lub cheeb tsam concentration, thiab kev hloov kho thev naus laus zis ib txhij. Saib tom ntej, raws li daim ntawv thov scenarios dhau los ua kom zoo dua qub thiab cov kev xav tau zoo nce ntxiv, kev ua lag luam yuav txhim kho ntxiv mus rau kev ua tau zoo, kev phooj ywg ib puag ncig, thiab kev hloov kho. Lub hom phiaj ntawm kev sib tw yuav hloov los ntawm kev nthuav dav mus rau kev tsim kho thev naus laus zis thiab txhim kho kev pabcuam dav dav.
