** Taw qhia
Kub yaj nplaum, feem ntau hu ua cov kua nplaum kub, yog ib hom thermoplastic nplaum uas yaj thaum rhuab thiab solidifies thaum nws txias. Nws yog ntau yam thiab txhim khu kev qha nplaum uas siv ntau yam kev siv, suav nrog kev ua haujlwm ntoo, ntim khoom, khoom sib dhos, thiab phau ntawv. Txawm li cas los xij, ib lo lus nug uas feem ntau tshwm sim ntawm cov neeg siv cov nplaum nplaum kub yog seb nws puas yog dej tsis zoo los yog tsis. Hauv tsab xov xwm no, peb yuav tshawb xyuas cov lus nug no kom tiav thiab muab rau koj kom nkag siab meej txog cov dej tsis zoo ntawm cov nplaum nplaum kub.
**Definition of Waterproof
Txhawm rau kom nkag siab seb cov nplaum nplaum kub yog dej tsis zoo los yog tsis, nws yog ib qho tseem ceeb uas yuav tsum tau ua ntej txhais tias peb txhais li cas los ntawm waterproof. Yooj yim muab tso, dej tsis zoo yog hais txog lub peev xwm ntawm cov khoom siv lossis cov khoom siv los tiv thaiv kev nkag mus ntawm dej. Qhov no txhais tau hais tias cov khoom siv lossis cov khoom yuav tsum tsis txhob tso dej los ntawm nws los yog ua rau nws tsis zoo thaum raug dej.
** Khoom ntawm Kub Melt Adhesive
Kub yaj nplaum nplaum yog ib hom tshwj xeeb ntawm cov nplaum uas paub txog nws cov khoom sib txuas ruaj khov thiab muaj peev xwm ceev ceev. Thaum rhuab, kub yaj nplaum hloov los ntawm cov khoom hauv lub xeev mus rau lub xeev ua kua, tso cai rau nws yooj yim mus thov rau qhov chaw. Nws solidifies yuav luag tam sim ntawd thaum nws txias, muab kev ruaj khov ntawm ob qhov chaw tau koom nrog.
Kub yaj nplaum kuj tseem paub txog nws txoj kev ua tau zoo thiab muaj peev xwm sib txuas rau ntau yam ntaub ntawv, suav nrog ntoo, yas, hlau, ntaub, thiab ua npuas ncauj. Nws kuj yog resistant rau cov kuab tshuaj thiab tshuaj, uas ua rau nws zoo tagnrho rau siv nyob rau hauv hnyav ib puag ncig.
** Puas yog Kub Melt Adhesive Waterproof?
Lo lus teb rau lo lus nug no tsis yog ncaj nraim, vim nws nyob ntawm ntau yam. Ua ntej, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kub yaj nplaum nplaum tsis yog dej tsis muaj dej. Nyob rau hauv nws cov khoom muaj zog, kub yaj nplaum nplaum tuaj yeem nqus dej thiab ua kom tsis muaj zog, uas tuaj yeem cuam tshuam nws lub zog sib txuas. Txawm li cas los xij, nws muaj peev xwm ua kom kub yaj nplaum nplaum tsis muaj dej los ntawm kev ntxiv qee yam additives lossis coatings.
Ib txoj hauv kev los ua kom kub yaj nplaum nplaum tsis muaj dej yog ntxiv cov txheej polyamide. Polyamide yog ib hom nylon uas yog dej-resistant thiab muab ib txheej ntxiv ntawm kev tiv thaiv rau kub yaj nplaum. Kub yaj nplaum nplaum nrog polyamide txheej yog feem ntau siv rau hauv daim ntawv thov uas yuav tsum tau tiv thaiv dej thiab ya raws, xws li hauv kev tsim cov nkoj thiab lwm yam khoom siv dej.
Lwm txoj hauv kev los ua kom kub yaj nplaum nplaum yog los ntawm kev ntxiv urethane additive. Urethane yog ib hom polymer uas yog dej-resistant thiab muab kev ruaj khov rau ntau yam ntaub ntawv. Kub yaj nplaum nplaum nrog urethane additive feem ntau yog siv rau sab nraum zoov daim ntaub ntawv, xws li nyob rau hauv kev tsim kho ntawm cov rooj tog zaum nraum zoov los yog nyob rau hauv lub installation ntawm sab nraum zoov cov paib.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov ua tau zoo ntawm cov tshuaj ntxiv no nyob ntawm daim ntawv thov thiab ib puag ncig. Yog tias cov nplaum nplaum kub kub raug dej rau lub sijhawm ntev los yog raug rau ib puag ncig hnyav, nws cov khoom tsis muaj dej yuav tsis muaj zog thaum lub sijhawm.
** Lus xaus
Nyob rau hauv xaus, kub yaj nplaum nplaum yog tsis inherently waterproof, tab sis nws muaj peev xwm ua kom nws waterproof los ntawm kev ntxiv tej additives los yog coatings. Kub yaj nplaum nplaum nrog polyamide txheej los yog urethane additive muab kev tiv thaiv dej thiab noo noo, ua rau nws tsim nyog siv rau sab nraum zoov thiab marine daim ntaub ntawv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog tej yam kev mob ntawm ib puag ncig thiab lub sij hawm raug dej thaum siv cov nplaum kub yaj hauv cov ntawv thov uas xav tau cov khoom tsis muaj dej.
