Isikhwama sephepha esinsundu

Isikhwama sephepha se-Kraft siyisitsha sokupakisha esenziwe ngezinto ezihlanganisiwe noma iphepha elihlanzekile le-kraft.Ayinabuthi, ayinambitheki, ayingcolisi, inekhabhoni ephansi futhi ayihambisani nemvelo.Ihlangabezana nezindinganiso zikazwelonke zokuvikela imvelo.Inamandla aphezulu kanye nokuvikelwa kwemvelo okuphezulu.Njengamanje ingezinye zezinto zokupakisha ezithandwa kakhulu emhlabeni jikelele.Izikhwama zephepha ze-Kraft zenziwe nge-wood pulp paper njengento eyisisekelo.Imibala ihlukaniswe ibe yiphepha elimhlophe le-kraft kanye nephepha le-kraft eliphuzi.Iphepha lingambozwa ngesendlalelo sezinto ze-PP ukuze lidlale indima engenamanzi.Amandla esikhwama angenziwa kusuka ku-1 kuya ku-6 izendlalelo ngokuya ngezidingo zamakhasimende., Ukuphrinta nokwenza izikhwama kuhlanganisiwe.Izindlela zokuvula kanye nekhava yangemuva zihlukaniswe ngokuvala ukushisa, ukuvalwa kwephepha nokunamathisela phansi.

Amandla aphukayo omdwebo wesikhwama esilukiweyo iyisixhumanisi sokulawula amandla esikhwama esilukiweyo.Indlela yokulawula amandla okuphuka komdwebo ukulawula ingxenye yezinto ezingavuthiwe, ukwakheka kokupholisa kwe-diaphragm namandla okuqina omdwebo.
Indlela yokukhiqiza ihlobene nemvelo kanye nezinto ezibonakalayo.I-filler ingenye yezingxenye eziyinhloko zengxenye yempahla eluhlaza, engathuthukisa izakhiwo zomzimba zebhulashi futhi inciphise izindleko.Lapho amandla kagesi wekepisi kagesi ekhula, amandla okudonsa ebhulashi azokwehla kancane kancane.Lokhu kungenxa yokuthi ingxenye eyinhloko ye-masterbatch yokugcwalisa i-calcium carbonate, engenakho ukungezwani, Ihlakazekile kugebe le-polymer chain ye-polyolefin, alikho ithonya elikhulu emandleni okudweba umdwebo, ukuze kuthuthukiswe ukuqina komdwebo.Lapho inani elingeziwe lingaphezu kuka-20% - 25%, i-masterbatch yokushaja izothatha isikhundla seketango le-polymer futhi ivimbele ukuguga okunwebekayo kwe-polymer, ukuze iketango le-polymer lingakwazi ukunyuswa ngokugcwele ngamandla angaphandle e-longitudinal.
