Umahluko kuYilo lwe-Screw Barel yokuBunjwa kweBhotile yokuVuthela kunye nokuBunjwa kwesitofu

I-Bottle Blow yokubumba i-screw barrel uyilo ime ngaphandle kokubumba inaliti ngenxa yobude bayo obude kunye nomlinganiselo ophezulu woxinzelelo. Oku kunceda ukudala iiparini ezifanayo, eziphucula ukucaca kwebhotile kunye namandla. Njengoko imarike yeplastiki ebunjiweyo yehlabathi ikhula, iUkuvuthela i-Screw BarelkwayeIfilimu evuthelweyo Screwhambisa ukunyibilika okusebenzayo, ukuxuba, kunye nokonga amandla phezu kweI-Plastic Screw Barel enye.

Umsebenzi we-Screw Barel kwiiNkqubo zokuBumba

Ukunyibilika kweMathiriyeli kunye neendima zokuHambisa

I-screw barrel isebenza njengentliziyo yabo bobabini ukuvuthela ibhotile kunye noomatshini bokubumba inaliti. Umsebenzi wayo ophambili kukunyibilikisa iipeliti zeplastiki kunye nokuhambisa izinto ezityhidiweyo phambili. Ekubunjweni kwesitofu, isikrufu sijikeleza ngaphakathi kombhobho oshushu, sicinezela kwaye sinyibilikisa iplastiki. Nje ukuba iplastiki inyibilike, isikrufu sityhalela kwimold ngoxinzelelo oluphezulu. Le nkqubo ibumba iplastiki kwiindawo eziqinileyo.

Ekubunjweni kwebhotile, i-screw barrel nayo iyayinyibilikisa ipholima. Nangona kunjalo, indlela ehambisa ngayo izinto inokutshintsha. Umzekelo, kwi-extrusion blow molding, i-screw inokujika ngokuqhubekayo okanye ngamanyathelo. Ityhalela ngaphandle iplastiki enyibilikisiweyo njengetyhubhu, ebizwa ngokuba yicawa. Emva koko umoya uvuthele kwicawe wenze ibhotile. Ekubumbeni ukuvuthela ngesitofu, isikrufu sifaka iplastiki enyityilisiweyo kwisingundo ukwenza i-preform, ethi kamva ibe yibhotile. I-screw barrel ilungelelanisa indima yayo ngokusekelwe kwinkqubo yokubumba, kodwa ihlala igxile ekunyibilikeni nasekuhambiseni iplastiki ngokufanelekileyo.

Ingcebiso:I-screw barrel eyenzelwe kakuhle iqinisekisa ukuba iplastiki inyibilika ngokulinganayo kwaye ihamba kakuhle, enceda ukukhusela iziphene kwimveliso yokugqibela.

Ukuxuba kunye ne-Homogeneity Effects

Ukuxuba kunye ne-homogeneity kudlala indima enkulu kumgangatho wemveliso. Umbhobho ojijwayo kufuneka udibanise iplastiki kunye naziphi na izongezo ukuze inxalenye yokugqibela ibonakale kwaye isebenze njengoko kulindelekile. Uyilo olwahlukileyo lwezikrufu lunokutshintsha indlela iplastiki exutywa ngayo kakuhle. Ngokomzekelo, izikrufu ezinamatshaneli akhethekileyo okanye amacandelo okuxuba anceda ukusabalalisa imibala kunye nezongezo ngokulinganayo. Oku kukhokelela kumbala ongcono kunye namabala abuthathaka ambalwa.

Abavelisi bahlala bevavanya ukuba isikrufu sixuba kangakanani na ngokujonga ubushushu kunye nombala weplastiki enyibilikisiweyo. Bajonga amaqondo obushushu alinganayo kunye nemixube yemibala egudileyo. A ngaphantsiukusuka kumngangathokwezi mvavanyo kuthetha ukuxubana ngcono. Ezinye izikrufu eziphambili, njengomqobo okanye uyilo lwe-multichannel, zibonisa ukuxubana okuphuculweyo kunye nokunyibilika okufanayo. Ezi mpawu zinceda ekudaleni iibhotile kunye namalungu aqinileyo, acacileyo, kwaye angenawo ama-streaks okanye amaqamza.
