Yog tias koj tau tuaj rau nplooj ntawv no, tej zaum koj yuav paub txog dab tsi gumboots yog dab tsi thiab qhov yuav tsum tau ua kom zoo, cov khau tsis muaj dej tsis zoo.Tab sis, koj puas tau nres xav, dab tsi yog khau nag ua los ntawm? Zoo, feem ntau cov khau tsis muaj dej yog tsim los ntawm cov roj hmab ntuj lossis polyvinyl chloride - cov khoom siv hluavtaws uas hu ua PVC lossis yas.
Ntuj roj hmab los ntawm latex (sap) ntawm tsob ntoo roj hmab (Hav brasiliensis) uas loj hlob thoob plaws ntiaj teb nyob rau hauv teb chaws sov biomes xws li Brazil, Thaib teb, thiab Indonesia.PVC, ntawm qhov tod tes, yog ib hom yas tsim hauv chav kuaj thiab muab tau los ntawm roj av.Muaj qhov zoo thiab qhov tsis zoo hauv kev ua haujlwm nrog cov xwm txheej lossis cov khoom siv hluavtaws vim txhua yam khoom muaj qee yam sib txawv nrog rau kev ua tau zoo, kav ntev, qhov hnyav, thiab pheej yig.
Ua ntej, cia peb tham txog cov roj hmab ntuj!Txhua tus neeg zoo siab gumboots yog tsim nrog cov roj hmab ntuj sab nrauv thiab ib leeg.Txhawm rau hloov los ntawm latex rau hauv roj hmab (thiab tom qab ntawd mus rau hauv koj lub gumboots), ntuj latex undergoes vulcanisation, txheej txheem tsim thiab patented los ntawm Charles Goodyear ntawm Goodyear log tsheb.Vulcanisation tempers cov roj hmab thiab tso cai rau nws yooj yim molded rau hauv lwm yam duab.Los ntawm qhov ntawd, nws yog tuag-cam khwb cia rau hauv cov duab nkhaus ntawm khau boots.Qhov no yog cov txheej txheem ntau lawm ntev dua li cov txheej txheem siv hauv kev tsim khoom siv PVC gumboots, tab sis qhov tshwm sim yog cov rwb thaiv tsev zoo dua, softness, thiab kev ua haujlwm tiv thaiv corrosion.
Lub durability, elasticity, thiab zoo ntawm cov roj hmab ntuj tuaj nrog kev lag luam tawm hauv qhov hnyav thiab tus nqi.Los ntawm nws qhov xwm txheej, roj hmab yog cov khoom hnyav dua li PVC, lub ntsiab lus roj hmab gumboots hnyav dua li PVC gumboots.Kev ua haujlwm ntawm phau ntawv koom nrog tapping latex los ntawm tsob ntoo roj hmab thiab ua nws rau hauv cov roj hmab kuj tseem kim dua li cov txheej txheem koom nrog hauv kev tsim PVC.Qhov no txhais tau hais tias ntuj roj hmab gumboots feem ntau kim dua PVC gumboots.Txawm li cas los xij, muaj kev sib pauv yuav tsum tau ua raws li tus nqi pib siab dua rau cov roj hmab ruaj khov yog them tawm hauv lub neej ntev ntawm cov khoom siv vim tias koj cov khau yuav tsis tas yuav tsum tau hloov ntau zaus.Peb ntseeg hais tias muaj nuj nqis tom qab durability thiab ntsuam xyuas tus nqi-ib-hnav ntawm koj cov gumboots thiab peb sawv ntawm qhov no nrog ib lub xyoo warranty ntawm peb cov khau.
Tam sim no cia peb tham txog PVC!PVC yog cov khoom siv hluav taws xob sib xyaw ua ke, ib feem, los ntawm cov roj av.Tsim PVC yog txheej txheem nyuaj uas muaj ntau yam chemistry, tab sis tam sim no nws kuj yog ib txoj kev nrov heev thiab pheej yig siv thoob plaws ntau yam kev lag luam.Txhawm rau hloov PVC rau hauv cov khau, cov pellets me me ntawm PVC yog yaj mus rau hauv cov kua dej, tom qab ntawd nchuav ib ncig ntawm lub khau raj pwm hauv cov txheej txheem hu ua txhaj-moulding.Kev txhaj tshuaj molding yog siv rau ntau yam ntawm cov haujlwm, ua rau nws cov txheej txheem pheej yig rau kev tsim thiab ua rau PVC khau boots yog ib qho kev xaiv uas tsis tshua muaj nqi rau cov dej tsis muaj dej thiab rau cov uas tab tom nrhiav cov khau looj plab hlaub.
