Indlela yokufumanisa umatshini wokuvavanya iprojekthi

1. Iindlela zovavanyo lwamandla okuqina kunye nobude ngexesha lekhefu
Umgangatho womgangatho: GB13022-91 "Indlela yovavanyo lweepropathi ezixineneyo zeefilimu zeplastiki"

Uhlobo lomfanekiso: Iindidi ze-I, II, kunye ne-III zii-dumbbells, kwaye Uhlobo lwe-IV luluhlu olude.Iisampulu zodidi lwe-IV zezona ziqhelekileyo.

Ukulungiswa kwesampuli: ububanzi buyi-15mm, ubude besampula abukho ngaphantsi kwe-150mm, kwaye ubude be-gauge buqinisekisiwe ukuba bube yi-100mm.Kwiisampuli ezinezinga elikhulu lokuguqulwa kwezinto, ubude be-gauge abuyi kuba ngaphantsi kwe-50mm.

Isantya sovavanyo: 500±30mm/min

Imiba efuna ingqalelo: Isampuli ifakwe kwii-clamps ezimbini zomatshini wokuvavanya, ukwenzela ukuba i-axis ye-longitudinal yesampuli ihambelane nomgca ophakathi we-clamps ephezulu kunye nezantsi, kwaye i-clamps iqinile ngokufanelekileyo.

2. Indlela yokuvavanya ukumiselwa kwamandla etywina lobushushu

Umgangatho womgangatho: QB/T2358-98 Indlela yokuvavanya amandla okutywinwa kobushushu bepakethe yefilimu yeplastiki.

Amanyathelo okuvavanya: thatha indawo yokutywinwa kobushushu njengeziko, uyivule i-180 degrees, ibambe zombini iziphelo zesampulu kwizinto ezimbini zokulungisa umatshini wokuvavanya, i-axis yesampuli kufuneka ihambelane nomgca osembindini wezinto eziphezulu kunye nezisezantsi. , kwaye ukuqina kufuneka kube ngokufanelekileyo.Umgama phakathi kwee-clamps yi-100mm, kwaye zitsalwa ngaphandle kwisantya esithile ukuze zifunde umthwalo xa isampuli iphula.Ukuba isampulu yaphukile kumdlalo, isampulu ayisebenzi.

3. Indlela yokuvavanya i-180 ° yokuzimisela amandla e-peel

Umgangatho womgangatho: bhekisa kwi-GB8808 ethambileyo ehlanganisiweyo yeplastiki indlela yovavanyo lokuxobula.

Ukulungiswa kwesampula: ububanzi buyi-15mm (ukutenxa akuyi kudlula i-0.1mm), ubude buyi-200mm;i-pre-peel 50mm ecaleni kwendlela yobude, kwaye akuyi kubakho monakalo ocacileyo kwindawo exotshiweyo ekuqaleni.

Ukuba isampuli ayilula ukuba ihlanjululwe, enye isiphelo sesampuli sinokucwiliswa kwi-solvent (edla ngokusetyenziswa ngokuqhelekileyo kwi-ethyl acetate kunye ne-acetone) malunga ne-20mm.

Ukusetyenzwa kweziphumo zovavanyo: Bala umndilili wamandla exolo ngokuthatha indlela yokuthatha amanani afanayo.Iyunithi yovavanyo yi-N/15MM.

Qaphela: Xa i-composite layer ingenakukhutshwa okanye i-composite layer iphukile, amandla ayo e-peel agwetywa ukuba afanelekile, kodwa amandla okuqina kufuneka aqinisekiswe ukuba afanelekile.
