Yiziphi izici ezithinta ukunamathela kwezinamatheliso ze-pur hot melt?

   Ama-meltadhesives ashisayo ashisayobabe nezindawo zokunamathisela ezihlukene ezinhlelweni ezahlukene. Uma ingcina ye-purhot melt ifuna ukusebenzisa ukusebenza kwayo kokunamathela okuphezulu, kuyadingeka ukuqonda izici zayo ezinkulu ezimbalwa, futhi ube nokuqonda okuphelele kwe-viscosity yokuqala kanye ne-viscosity ehlala isikhathi eside. Namuhla sizochaza izinto ezimbalwa ezithinta ukunamathela kwe-pur hot melt:

1. Umbala:

Kuzinto zokunamathisela ezincibilika ezishisayo, imibala ehlukene ine-viscosity ehlukene, futhi ingcina ephuzi ingcono ngemibala eminingi.Uma ukusebenzisa ingcina enombala kungenamthelela entweni eboshiwe, kunconywa ukuthi ukhethe iglue ephuzi encibilikayo, umphumela wokunamathisela muhle kakhulu.

2. Izinga lokushisa:

I-Pur hot melt adhesive izwela kakhulu izinga lokushisa. Lapho izinga lokushisa lifinyelela iphuzu elincibilikayo, ingcina iqala ukuthamba. Uma izinga lokushisa lidlula izinga lokushisa elijwayelekile lokusebenzisa, ingcina ye-thepur hot melt izoba brittle, okuzothinta kakhulu umphumela wokubopha. Izinga lokushisa elisebenzayo le-pur hot-melt adhesive liphansi kunele-EVA hot-melt adhesive, ngakho-ke umshini wokunamathela we-pur hot-melt kufanele ulawule ngokuqinile izinga lokushisa elisebenzayo leglue ngayinye lapho usebenza, futhi udinga ukucabangela ngokuphelele ushintsho lokushisa kwemvelo.

3. Isikhathi sokuphumula:

Abantu banamuhla banomqondo wesikhathi oqinile kakhulu, futhi amakhasimende ayafana. Ngemva kokufaka i-oda, bonke bathemba ukuthi bangalethwa kubo ngokushesha ngangokunokwenzeka. Lokhu kudinga ukuthi izinkampani ziqedele ngokusebenza kahle kokukhiqiza. Ukucubungula okusheshayo kuwumkhuba.Amandla e-pur hot melt adhesive ukuthi isikhathi sayo sokuphulukisa sifinyezwa kakhulu uma siqhathaniswa nezinye izingcina, ngokuvamile cishe imizuzwana engu-6-20. Kodwa-ke, ukusebenza kahle kulandelwa kakhulu, isikhathi sokwelapha esinganele sisazothinta umphumela wokubopha.

4. I-Viscosity:

I-viscosity ye-pur hot melt adhesive ihlukaniswe yaba yi-viscosity yokuqala nokubamba i-viscosity. I-viscosity yokuqala imelela i-viscosity ye-adhesive, futhi i-viscosity yokubamba imelela amandla okunamathela okunamathelayo. Ngokuvamile kungcono ukukhetha ingcina efanele. Ihlobene ngokuqondile. Uma umphumela wokunamathela wokuqala ungemuhle, asikho isidingo sokukhuluma nge-viscosity yokubamba ekugcineni. I-viscosity yokuqala inobudlelwano obukhulu nemvelo lapho okunamathelayo kutholakala khona.
