Kodi pali kusiyana kotani pakati pa thovu ndi siponji?

Kusiyana kukadali kwakukulu.

Mawonekedwe a thovu la EVA: Osalowa madzi: mawonekedwe a thovu otsekedwa, osayamwa chinyezi, osalowa madzi, osagwira ntchito bwino madzi.

Kulimbana ndi dzimbiri: kugonjetsedwa ndi dzimbiri za mankhwala monga m'madzi, mafuta a masamba, asidi, alkali, ndi zina zotero, antibacterial, non-poizoni, osanunkhiza, komanso osaipitsa.

Njira yogwirira ntchito: palibe zolumikizira, zosavuta kupondaponda, zodula, zomatira, zothandizira ndi kupanga ndi kukonza kwina.

Kukana kugwedezeka: kulimba mtima kwambiri, kukana chithandizo chachikulu, ductility yayikulu, kukana kugwedezeka kwabwino komanso kutsika.

Kutentha kwa kutentha: kutsekereza kutentha, kutchinjiriza kutentha, antifreeze, kutentha kwambiri, kuchita bwino kwambiri, kukana kuzizira komanso kukana dzuwa.

Kutsekereza kutentha: mabowo otsekedwa, kutsekereza mawu komanso kuchepetsa phokoso ndizabwino kwambiri.

Siponji ndi EVA thovu.

Kusiyana: PVA siponji: Acrylic emulsion ndi condensation anachita wa akiliriki emulsion ndi formaldehyde zili, ndi yamkaka woyera kapena kuwala yellow amorphous olimba.

Malo osungunuka ndi apamwamba kuposa a homologous acetal (140 ~ 150 ℃), mphamvu yopondereza, kuuma ndi mphamvu ndizokwera, ndipo ntchito yomangira ndi yabwino kwambiri;ndi bwino kuvala kukana ndi kusungunula zipangizo zamagetsi;kukana madzi komanso dzimbiri, kukana kwa alkali wabwino.

Kutentha, utsi wakuda kuchokera ku chitoliro chotulutsa mpweya.

Kusungunuka ndi kudontha, ndi fungo lapadera.

Thonje la thonje: kachulukidwe kakang'ono, kuyamwa kwamadzi mwamphamvu, thonje lolimba kwambiri, ductility wabwino, kukana kuvala bwino, kosavuta kukanda, kosavuta kukanda, kosavuta kutsitsa.

Pambuyo particles ndi madzi kulowa kuwira dzenje, si kophweka kugwa kapena kufinya pa chifuniro, ndipo ali ndi luso kutseka.

Thonje la Bubble ndi kapangidwe kake ka elastomer, komwe kamapangidwa ndi guluu wapadera wa phenolic resin wokhala ndi mawonekedwe olumikizana ndi mankhwala.

Imakhala ndi mayamwidwe owoneka bwino amadzi mu molekyulu.

Mosiyana ndi siponji wamba wa urethane, chithovu cha polyvinyl chloride chimakhala ndi mayamwidwe ambiri amadzi, ndipo capillary chodabwitsa chimayamba chifukwa cha ma pores oyenda, kupereka kusewera kwathunthu pakuyamwa kwabwino kwa chinyezi komanso kutseka kwamadzi.
