1. Rudzi rwekupisa kunyunguduka kwakanamatira firimu: (chete rudzi rwemhando yemhando inopisa inonyungudika yakanamatira inokurukurwa pano)
Rudzi rwemhando yeadhesive inopisa inonyunguduka inonyanya kukamurwa zvichienderana neyakabikwa, iyo inogona kukamurwa kuita: PA inopisa inonyunguduka adhesive (ine firimu uye omentum), PES inopisa inonyunguduka adhesive (ine firimu uye omentum), TPU inopisa kunyunguduka adhesive (ine Adhesive firimu uye omentum), EVA inopisa inonyunguduka inonamatira (ine inonamira firimu uye omentum).
Imwe neimwe yemhando dziri pamusoro peanopisa anonyungudutsa anonamatira anogona kukamurwa kuita akasiyana mamodheru zvichienderana nekunyungudika, hupamhi, ukobvu, kana girama. Panguva imwecheteyo, maitiro avo akasiyana zvakare:
(1) PA hot melt adhesive: ine maitiro ekuomeswa kwekuchenesa uye kushambidzika kuramba, kushomeka kwekushisa kusvika kune minus 40 madhigirii, kupikisa kwekushisa kwepamusoro pamusoro pe120 degrees; inoshanda PA inopisa melt adhesive ine maitiro emurazvo retardancy uye kuramba kune iri kufashaira mvura pa100 madhigirii;
(2) PES inopisa inonyunguduka adhesive: ine hunhu hwekuwachisa kuramba uye yakaoma kuchenesa kuramba, kushoma tembiricha kuramba kusvika minus 30 madhigirii, yakakwirira tembiricha kuramba pamusoro 120 madhigirii, uye yakakwirira bonding simba;
(3) EVA inopisa-yakanyunguduka yakanamatira: kushongedzwa kushoma kushambidzika, kwete kuoma-kuchenesa kuramba, kunyungudika kwakadzika, kushomeka kwekushisa kweiyo minus 20 madhigirii, kupisa kwakanyanya kwe80 degrees;
(4) TPU inopisa melt adhesive: ine hunhu hwekuwachisa kuramba, kwete yakaoma kuchenesa kuramba, kushoma tembiricha kuramba minus 20 madhigirii, yakakwirira tembiricha kuramba 110 madhigirii, yakanaka tensile zvinhu, uye kupfava;
Izvo zviri pamusoro apa maitiro akakodzera ekupisa kunyunguduka adhesives emhando dzakasiyana. Kunzwisisa maitiro aya kwakakosha pakusarudzwa kwemafirimu ekunamatira anopisa anonyungudika. Naizvozvo, isu tinofanirwa kutarisisa kune ayo echigadzirwa maitiro uye chaiwo mashandisiro pakusarudza inopisa inonyungudutsa inonamatira mafirimu, kuitira kuti tidzivise dambudziko rekusarurama hot inonyungudutsa adhesive firimu kusarudzwa kana kushandiswa zvisina kunaka.
Uyewo teerera kune zvidziviriro zveimwe neimwe inopisa inonyunguduka inonamira firimu panguva yekushandiswa, sekudzvanya tembiricha, kudzvanywa, kudzvanya nguva, nezvimwe.
