Indlela yokugweba umgangatho weglue ukuze kuphuculwe amandla okubopha kwikhadibhodi ebotshelelweyo itshokholethi zebhokisi yemini yezithandani
Amandla okuncamathela kwekhadibhodi ebotshelelweyo axhomekeke kakhulu kumgangatho weglue kunye nomgangatho wobungakanani bomgca wokuvelisa ikhadibhodi ebotshelelweyo.ibhokisi yetshokholethi yosuku lwezithandani
Umgangatho wokuncamathelisa ibhokisi yetshokholethi yeValonia
Umgangatho weglue uxhomekeke kakhulu kwiingenelo kunye neengxaki zenkqubo yokwenza iglue kunye nomgangatho wezinto ezisetyenzisiweyo. Izinto ezisetyenziswa kakhulu kwiglue yistarch, kwaye icornstarch engaphezulu komgangatho wemizi-mveliso isetyenziswa ngokubanzi. Ukuba kusetyenziswa iglue ekumgangatho ophantsi, ngenxa yokuba ayisebenzi kakuhle kwaye ingcola efana neproteni namafutha, iya kusebenzisa i-caustic soda eninzi, nto leyo eyenza iglue ingaguquguquki, kwaye ikhadibhodi ebotshelelweyo kulula ukuyifunxa umswakama, kwaye iglue Kulula ukuvelisa ijeli ene-starch granules ezinkulu kunye nokungcola njengesiseko, nto leyo eyenza ukuba ukunyibilika kube kubi ngakumbi. itshokholethi ezifakwe kwibhokisi yeWalmart
Umxholo oqinileyo, i-initial tack, i-viscosity, ubushushu bokuncamathisela, njl.njl. zizinto ezibalulekileyo zokulinganisa umgangatho we-adhesives: Ibhokisi yetshokholethi yeGodiva eneziqwenga ezingama-36
1. Umxholo oqinileyo ibhokisi yesipho setshokholethi ye-amazon
Umxholo oqinileyo weglue kufuneka umiselwe ngokuchaneka kwezixhobo, isantya sokusebenza kunye nemeko yokwenyani yephepha lesiseko. Nje ukuba isantya somgca wokuvelisa ibhodi yeglue ebanzi ekhawulezayo sifikelele kwi-200 m/min nangaphezulu, umxholo oqinileyo weglue kufuneka ube phezulu. Amanzi kunye nesitatshi Umlinganiselo uhlala uphakathi kwe-2.5:1-3:1. Okukhona umxholo oqinileyo weglue uphezulu, kokukhona umswakama uya kuba mncinci. Inani elincinci leglue linokuqinisekisa ukunamathela kwebhodi yeglue ehlanganisiweyo; kwaye utshintsho lomswakama kwinkqubo yokucubungula amakhadi yeglue ehlanganisiweyo luncinci, okunokunciphisa ukugoba kwekhadibhodi ehlanganisiweyo. Ukuba ukuchaneka kwezixhobo zeshishini kuphantsi, isantya sesithuthi sicotha, kwaye iphepha lesiseko kulula ukulibona, umxholo oqinileyo weglue kufuneka ube phantsi, kungenjalo kuya kubangela iingxaki zomgangatho ezifana nokususa igum yekhadibhodi ehlanganisiweyo, ukukristala kwemigca yentlama, kunye nokuqhuma kwemigca. iitshokholethi zebhokisi ezilungileyo
2. i-tack yokuqala ibhokisi yetshokholethi engcono yesipho
Ukubopha kokuqala ngundoqo ekuqinisekiseni ukunamathela kwekhadibhodi ebotshelelweyo kunye nokwandisa isantya somatshini. Ekuveliseni ikhadibhodi ebotshelelweyo, ukwandisa indawo yokufudumeza kwangaphambili kwephepha elisisiseko, okanye ukongeza i-arhente yokudibanisa xa usenza i-adhesive, ukongeza i-borax kumzimba oyintloko kunye netanki yokuthwala ngokwahlukeneyo, kunye nokwandisa umxholo oqinileyo we-adhesive kunokwenza i-adhesive igqunywe. Emva kwexesha elifutshane, iqala ukuvelisa amandla okunamathela, kwaye amandla ayo okunamathela anokutshabalalisa imicu yephepha. ibhokisi yetshokholethi engcono kakhulu yezithandani
3. ukuxinana ibhokisi yetshokholethi yesipho esingcono kakhulu
Okukhona i-viscosity ye-glue iphantsi, kokukhona ukuhamba kwayo kungcono. Ukutyibilika kwe-glue kumisela ukuvuleka kwe-glue, ukufana kwe-glue kunye nobungakanani be-glue, nto leyo echaphazela ngokuthe ngqo isantya somatshini, ukunamathela kwekhadibhodi, ukuba tyaba kunye namandla ekhadibhodi. Ukongeza, ayikuko ukuba xa umlinganiselo wesitatshi uphezulu kwi-glue, kokukhona ukutyibilika kusiba kubi; i-glue enomxholo ophezulu oqinileyo inokugcina i-viscosity ephantsi kakhulu ngokulungisa inkqubo yokulungiselela. Kwiimeko eziqhelekileyo, i-viscosity ye-glue iya kuncipha ngalo lonke ixesha idlula kwimpompo yokujikeleza ngexesha lokujikeleza. Ngeli xesha, kufuneka ixutywe ne-glue entsha eyenziweyo.
4. ubushushu be-gelatinization
Ubushushu be-gelatinization bubhekisa kubushushu bokuqala obufunekayo ukuguqula i-starch binder ibe yintlama. Ubushushu be-gelatinization ye-binder yinto ephambili yokugcina imveliso ekhawulezayo. Ukusombulula ingxaki yobushushu be-gelatinization ye-binder, ukongeza ekulungiseni i-caustic soda Ukongeza kwidosi kunye nendlela yokufudumeza, isiphumo esifanayo sinokufezekiswa ngokongeza ezinye izongezo ngokufanelekileyo. Ubushushu be-gelatinization akufuneki bube phantsi kakhulu, kungenjalo buya kubangela i-gelatinization ye-adhesive ngexesha lokujikeleza kwegazi kwaye buchaphazele ukugeleza kwe-adhesive. Ubushushu be-gelatinization ye-adhesive kufuneka buhlengahlengiswe ngokweenguqu zexesha lonyaka. Ebusika, ubushushu be-gelatinization bunokwehliswa bube ngama-55-60°C, kwaye ehlotyeni, ubushushu be-gelatinization bunokulungiswa bube ngama-61°C-66°C.
Ubungakanani bomgangatho womgca wokuvelisa amakhadibhodi anezikhonkwane
EYurophu nase-United States, uhlolo olubalulekileyo lomgangatho weebhokisi ezirhabaxa kukuhlolwa kobubanzi bomgca weglue webhodi erhabaxa. Ubungakanani obuqhelekileyo kukuba indawo ichanekile, iglue isetyenziswa ngokulinganayo nangokuthe tye kwiflute yonke, umgca weglue ucacisiwe ngokucacileyo, kwaye akukho mfanekiso weglue ecaleni ovela kwi-corrugation, kwaye akukho migca yeglue erhuqwayo.
Ubungakanani obubi buxhomekeke kakhulu kwimeko yezixhobo zomgca wokuvelisa ibhodi ebotshelelweyo, umgangatho weglue, kunye nomgangatho wephepha elisisiseko.
Iingxaki eziqhelekileyo zomgangatho ezibangelwa bubungakanani obungalunganga zibonakala kakhulu kwezi nkalo zilandelayo:
1. I-Drip glue phenomenon
Kukho ukungcola kwirola ephezulu, njengee-paper scrap, i-starch agglomerates kunye nezinye izinto zangaphandle, okanye kukho izinto zangaphandle ezivala iiseli kumphezulu werola, ukuze irola ephezulu ingakwazi ukuncamathiselwa kakuhle, kwaye kunokuthi kudluliselwe inani elincinci le-glue, kwaye kulula ukuyisula. Xa incamathiselwa, akuyi kubakho glue yaneleyo kwincochoyi ye-corrugated, kwaye kuya kubakho ukuvuza kwe-gluing okuthe ngcembe. Kuya kubakho iimpawu zokwahlukana phakathi kwephepha lomphezulu kunye nephepha eliphambili kumphezulu wekhadibhodi enjalo, kwaye amandla oxinzelelo, amandla oxinzelelo lomphetho kunye namandla okuncamathisela ekhathoni aya kuncipha.
Xa umsantsa phakathi kwerola yerabha ephezulu kunye nerola ye-corrugating esezantsi ubanzi kakhulu, irola yerabha ephezulu ayinakuyichukumisa irola ye-corrugating esezantsi, kwaye akukho glue yaneleyo kwincochoyi ye-corrugating.
2. I-Adhesive Transversal Projekthi ye-Adhesive Transversal
Ukuba i-viscosity ye-glue iphezulu kakhulu; ukuba iphantsi kakhulu okanye umxholo we-borax kuyo uphezulu kakhulu, kulula ukuba i-glue idubule ecaleni xa umgca wemveliso usebenza ngesantya esiphezulu, nto leyo eya kubangela ukuba ikhadibhodi igobe okanye ithambe, kwaye uxinzelelo lwe-bonding kunye necala le-cardboard kunye namandla okucinezela ziya kuncipha.
