A halin yanzu, akwai nau'ikan nau'ikan nau'ikan anti-manne da aka saba amfani da su don buɗe bakin baki,oleic acid, erucic acid da silicon dioxide.Hakanan akwai wasu bambance-bambance a cikin takamaiman nau'ikan da hanyoyin amfani.Wannan takarda ya fi kwatanta bambance-bambancen da ke tsakanin abubuwa uku a cikin budewa mai santsi da anti adhesion.
1. Taƙaitaccen gabatarwar wakili mai laushi mai buɗewa
(1) Oleic acid
Oleic acid amide, kuma aka sani da oleamide;(Z) - 9-Octadecylic acid amide.Yin amfani da shi a cikin fim din polyethylene zai iya rage rikice-rikice tsakanin fim din na ciki da kayan aiki a lokacin aiki, kuma yana da sauƙi don ƙaddamarwa, don haka ƙara yawan fitarwa da inganta haɓakar samfurin.(Saboda ƙananan adadin ƙara (0.1-0.15%) a cikin fim ɗin, dole ne a ƙara shi a cikin nau'i na cakuda ko babban tsari a cikin masana'antar sarrafawa don tabbatar da ingantaccen tasiri mai kyau.)
Gabaɗaya magana, oleic acid amide yana ƙaura zuwa saman ƙasa da sauri, amma ƙarancin juzu'i na dogon lokaci na erucic acid amide ya yi ƙasa da na oleic acid amide, kuma kwanciyar hankali na thermal na erucic acid amide ya fi na oleic acid amide.
(2) Erucic acid
Erucic acid amide ne yafi amfani da matsayin smoothing wakili da anti adhesion wakili ga CPP, BOPP, LDPE, LLDPE, EVA, PVC, PVDF, PVDC, PU, metallocene polyethylene da sauran robobi, wanda zai iya rage tsauri da kuma a tsaye gogayya coefficient na da samfurin (fim ko takardar) surface, da kuma inganta processability da marufi yadda ya dace.
(3) Siliki
Babban manufar
1) Rike babban kyalkyali na fim din.
2) Tare da babban yanki na musamman da kuma ƙarfin juriya mai ƙarfi, yana da matukar dacewa don amfani da shi azaman wakili mai buɗewa a cikin kayan fim.
3) Yana da kyau dispersibility kuma za a iya ko'ina tarwatsa a cikin guduro yin 10-25% anti manne master tsari.Ana iya amfani dashi don PP, PE da sauran samfuran fim.
2. Aikin Budaddiyar Baki Mai Sassauta
Dalilin da ya sa fim ɗin ba shi da sauƙi a raba shi ne, yanayin matsananciyar yanayi yana samuwa a tsakanin fina-finai bayan an rufe fim ɗin, don haka ba a samun sauƙin rabuwa;Wani kuma shi ne akwai sarƙoƙi masu yawa da aka fallasa a saman fim ɗin bayan an yi fim ɗin.Bayan an rufe fina-finai guda biyu, sarƙoƙi na macromolecular suna haɗuwa da juna, yana sa ba zai yiwu a buɗe ba.A haƙiƙa, dalilin wahalar buɗewar membrane shine kasancewar juna biyu, kuma na ƙarshe shine babban dalili.
3. Bambanci na aiki na oleic acid amide, erucic acid amide da silicon dioxide
Wakili mai laushi: ƙara kayan shafa mai laushi a cikin fim ɗin kamar ƙara ruwa ne tsakanin gilashin biyu.Kuna iya zame gilashin biyu cikin sauƙi, amma yana da wuya a raba su.
Wakilin buɗewa: ƙara wakili mai buɗewa ko buɗe masterbatch a cikin fim ɗin kamar roughening saman tsakanin gilashin biyu da takarda yashi.Kuna iya raba gilashin biyu cikin sauƙi, amma da kyar za ku iya zame su.
Bude masterbatch: abun da ke ciki shine silica (al'amarin inorganic) babu ƙaura
Smooth masterbatch: bangaren amide (kwayoyin halitta) babu ƙaura.
Lura: A halin yanzu, babban aikin ƙara wakili mai laushi zuwa fim ɗin filastik shine canza kayan zamewa da ƙarancin ɗanɗanowar fim ɗin ta hanyar rage girman juzu'i na fim ɗin.
(1) Oleic acid
Ƙarin adadin fim din amide na oleic acid yana da ƙananan (0.1-0.15%), wanda dole ne a ƙara shi a cikin nau'i na cakuda ko babban tsari a cikin masana'anta don tabbatar da santsi iri ɗaya.Oleic acid amide yana da tasiri mai kyau na budewa akan PE, kuma ana iya raba shi da sauri, kuma ana iya saduwa da buƙatun tare da ƙananan ƙarami.Duk da haka, yana da rauni mai mutuwa, kamar dandano mai ƙarfi da rabuwa da sauri, wanda ke shafar corona da bugawa.Hakanan yana da tsauraran buƙatu don zafin jiki.Adadin oleic acid amide ya bambanta a lokacin rani da hunturu.Bugu da ƙari, an kuma ƙara shi zuwa saman Layer da core Layer tare da kulawa sosai.
(2) Erucic acid
Erucic acid yana da santsi mai ƙarfi, ƙarancin hazo, juriya mai zafi, kuma ba shi da sauƙin juya rawaya.Yana da fa'ida a bayyane akan oleic acid.
Alal misali, a matsayin sabon marufi abu, BOPP yana da wani marufi gudun har zuwa 500 ~ 800 fakiti a minti daya, kuma ta gogayya factor dole ne ≤ 0.2.Sai kawai ta ƙara erucic acid amide (kimanin 0.12%) za mu iya samun madaidaicin abubuwan juzu'i.
Bugu da ƙari, yin amfani da shi kadai, alal misali, fim din PP mai busa tare da manyan buƙatun don santsi yana haɗe tare da erucic acid amide da oleic acid amide a cikin ainihin samar da tsari don cimma sakamako mafi kyau.
(3) SiO2 anti adhesion wakili
SiO2 anti mannewa wakili (bude wakili) za a iya ko'ina tarwatsa a cikin fim, forming da yawa lafiya da kuma wuya protrusions a kan fim surface, don haka rage lamba yankin tsakanin fina-finai, cimma manufar rage fim surface gogayya coefficient, yin fim. sauki bude.Hakazalika, kasancewar waɗannan fitattun abubuwan yana sa iskan waje ya sauƙaƙa shiga tsakanin fina-finan biyu, tare da gujewa samuwar vacuum tsakanin fina-finan biyu, Ta yadda za a hana mannewar fim.Amsa ga "Shuangshuai" don ƙarin labarai
4. Yadda za a zabi additives?
A cikin budewa da santsi masterbatch, zaɓi na amide da silica suna da mahimmanci ga aikin masterbatch.
Domin ingancin amides bai yi daidai ba, kuma abubuwan da ke tattare da rashin inganci za su sa masterbatch ya ɗanɗana girma kuma akwai baƙar fata a kan membrane lokacin da ya fito daga cikin membrane.Abubuwan da ke haifar da su ta hanyar ƙazanta da yawa a cikin man dabbobi.Sabili da haka, a cikin tsarin zaɓi da amfani, ya kamata a ƙayyade bisa ga aiki da amfani da amide.
Zaɓin silicon dioxide ya fi mahimmanci.Girman ƙwayar ƙwayar cuta, takamaiman yanki na yanki, abun ciki na ruwa, jiyya na ƙasa, da dai sauransu suna da tasiri mai mahimmanci akan samar da babban tsari da kuma aiwatar da cire fim.
