Vanhu vazhinji vanobvunza kanaduct tapenekuti kuvandudzwa kwemba kunoenderana nemhoteredzo, senge ine chepfu kana kuti ine formaldehyde, nezvimwewo. Ipapo tichazoongorora kubva kune yakabikwaduct tapenhasi.

Tepi yemuchekainoumbwa ne polyethylene uye gauze thermal composite sechinhu chakadzika, chakaputirwa nepamusoro-viscosity synthetic adhesive tepi.Iine huwandu hwakawanda hwekushandisa.

Chokutanga pane zvose, polyethylene uye gauze ndiyo nheyo yezvinhujira tepi.Polyethylene inonzi PE.Iyo thermoplastic resin inowanikwa ne polymerization ye ethylene.Polyethylene haina hwema, inodzivirira tembiricha, asidhi uye alkali inoshingirira, uye ine kugadzikana kwakanaka kwemakemikari.Mabhegi epurasitiki anowanzo shandiswa, mavharo emidziyo akavharwa ekicheni zvese zvigadzirwa zve polyethylene, uye gauze inozivikanwa kune wese.Yese donje ishamwari yezvakatipoteredza uye yakasununguka isina chero zvinhu zvinokuvadza.Icho chinhu chakakosha mbishi indasitiri yezvipfeko uye machira.

Zvadaro, ngatitarisei glue yeduct tape. Machira matepiakaiswa muzvikamu zvinopisa zvinonyunguduka zvinonamira uye rubber zvinoenderana neayo anonamira maitiro.Hot melt adhesive imhando yeadhesive yepurasitiki, chimiro chayo chemuviri chinoshanduka nekuchinja kwekushisa mukati meimwe tembiricha yemhando, asi makemikari ayo anoramba asina kuchinjika, Haina chepfu uye isinganakidze, uye ndeye yezvakatipoteredza zvine hushamwari kemikari chigadzirwa.Rabha rinoshandiswa mukugadzira matepi kazhinji rabha rechisikigo, uye rabha rechisikigo rinonyanya kutorwa kubva mumiti yerabha, saka zvakare haina chepfu uye haina kukuvadza.
