1. Ka'idoji da halaye na asali na thermoforming

Tsarin Thermoforming wata hanya ce ta musamman ta sarrafa filastik don sarrafa zanen thermoplastic zuwa samfura daban-daban. Ana dumama zanen thermoplastic don yin laushi sannan a matse shi (vacuum ko positive pressure) don sanya zanen thermoplastic ya yi aiki a saman mold don samun siffar kama da ta saman mold, kuma bayan sanyaya da siffa, ana gyara samfurin don samun siffar da ake so. Tsarin Thermoforming yana da sauri kuma iri ɗaya, tare da ɗan gajeren lokacin zagayowar mold da ƙarancin kuɗin mold, ya dace da sarrafa kansa da tsawon lokacin samarwa, kuma ana ɗaukarsa a matsayin hanyar sarrafawa mafi inganci tare da mafi ƙarancin farashin naúrar tsakanin hanyoyin ƙera filastik. Musamman tare da ci gaba da inganta tsarin thermoforming da kayan aiki da kuma shiga tsakani na kwaikwayon kwamfuta, tsarin thermoforming ya zama babban hanyar sarrafawa wanda ke fafatawa da allura da ƙera busa. A cikin 'yan shekarun nan, an sami sabbin ci gaba a cikin kayan aikin sarrafa thermoforming. Jimin ya gabatar da kayan aikin thermoforming da hanyoyin da aka nuna a K2013 a Jamus, inda sauri, iyawa, fasahar sarrafawa da rage farashi suka zama manyan jigogi ga sabbin kayan aiki don thermoforming a cikin marufi da masana'antu.

Manyan nau'ikan thermoforming sune: ƙirƙirar injin tsotsa, ƙirƙirar matsi, ƙirƙirar da aka taimaka wa plunger da haɗuwa da su.

Manyan robobi da ake amfani da su a thermoforming sune polystyrene (PS), polyvinyl chloride (PVC), polyolefins kamar PE, PP, polyacrylates (PMMA) da cellulose kamar nitrocellulose (NC), cellulose acetate (CA), da sauransu. Injiniyoyi na robobi kamar suacrylonitrile-butadiene-styrene (ABS)Ana kuma amfani da su. Filastik na Styrene (ABS), polycarbonate (PC), da sauransu. Ci gaban PP mai aiki kamar babban bayyananne, ƙarfin narkewa mai yawa da ƙarancin warpage ya haɓaka aikace-aikace da haɓaka PP a fannin thermoforming.

2. Matsayin Kasuwar Marufi Mai Tsarin Thermoforming ta Cikin Gida

Akwai kamfanonin shirya marufi na thermoforming na cikin gida sama da 3,000, waɗanda sama da 300 ke da fitar da tan 1,000 a kowace shekara. Kimanin kashi 70% na masana'antun da ke da ƙarfin samar da dubban tan a kowace shekara su ne zanen gado da kansu da kuma masu haɗa kayayyakin thermoformed. PS (OPS) da polyethylene terephthalate (PET) su ne manyan zanen gado na waje, yayin da wasu masana'antu masu ƙwarewa ke samar da zanen gado na PP, PS da PVC nasu, kuma ƙananan masana'antu suna fitar da zanen gado na waje. Ana amfani da samfuran thermoformed galibi a cikin marufi na abinci, marufi na abinci da zanen gado na yanke, kuma buƙatun kayan aiki sun bambanta daga aikace-aikace zuwa aikace.

3. Ci gaban PP don thermoforming

Aikace-aikacen thermoforming na PP na cikin gida ya fara ne a shekarun 1990 kuma yana ci gaba cikin sauri a cikin 'yan shekarun nan, tare da ƙimar ci gaba na kusan kashi 10% a shekara. Yanzu akwai manyan masana'antun marufi na filastik na thermoforming a China, kamar Japan Central Chemical, waɗanda suka gina masana'antu a China suka kuma sanya su cikin samarwa, kuma samfuran su galibi suna mai da hankali kan samfuran marufi na thermoforming na filastik matsakaici da babban inganci. A halin yanzu, akwai ƙarancin kayan PP na musamman musamman don tsarin thermoforming a China. Masana'antun samfuran thermoforming na cikin gida gabaɗaya suna siyan T30S da sauran resin manufa gabaɗaya waɗanda aka gyara don amfani, amma samfuran da aka samu ta hanyar gyare-gyare bayan gyare-gyare da samar da samfuran masana'antu, akwai ikon sarrafawa mara daidaituwa, kaddarorin tensile ba su cika buƙatun ba, kauri bango mara daidaituwa a cikin thermoforming, rufin extrusion calendering gefen curling da sauran matsaloli, yana da wuya a cika babban inganci da babban buƙatun buƙatun aikace-aikacen, amma kuma yana da wuya a biya buƙatun inganci da babban buƙatu, kuma yana iyakance ingancin samarwa na kamfanonin sarrafawa na ƙasa.

Kayan musamman na thermoforming na ƙasashen waje galibi homopolymers ne, masu nuna bazuwar copolymers ba su da yawa, kuma wasu maki suna da dogon zangon shigo da kaya, don haka masana'antun thermoforming na cikin gida ba sa amfani da kayan da aka shigo da su. Samar da takardar da ke akwai na masana'antun samfuran thermoforming galibi faɗin takardar mm 600 ne, tare da ci gaban fasahar injin ƙera kayayyaki, faɗin takardar yana ƙaruwa, mafi faɗi zai iya zama fiye da mm 1000, don haka ikon hana narkewar takardar don gabatar da buƙatu mafi girma. Mafita a masana'antar samfuran da ke ƙasa ita ce a ƙara wani kaso na polyethylene mai yawa (PE-HD) zuwa ga PP na yau da kullun don inganta juriyar narkewar takardar, amma wannan hanyar za ta kawo gaurayawa mara daidaituwa da ƙarancin bayyanawa na samfura. Masana'antar thermoforming na cikin gida tana da buƙatar gaggawa ga kayan PP tare da babban aiki da kuma bayyanawa mai matuƙar girma.
Kafin shekarar 2012, bincike da haɓaka kayan thermoforming masu haske a China sun kasance a baya kaɗan. A wancan lokacin, yanayin bincike da haɓakawa na kayan thermoforming na gida an jera su a cikin Tebur na 2.

Babu wani daga cikin waɗannan kayan aikin na musamman da aka ƙara yin aiki a kai don ƙarfin narkewa mafi girma da kuma rarraba nauyin ƙwayoyin halitta da ake buƙata don sarrafa thermoforming, kuma wasu ba a samar da su a babban sikelin ba.

A cikin 'yan shekarun nan, Tianjin Petrochemical ta ci gaba da haɓaka kayan aiki na musamman a fannin PP thermoforming, kuma ta sami fa'idodi masu yawa na tattalin arziki da zamantakewa, wanda ya ƙara launi ga wannan yanki na musamman na thermoforming.

Tebur na 4 yana nuna kayan PP na musamman don thermoforming da masana'antun petrochemical da yawa suka haɓaka a cikin 'yan shekarun nan, waɗanda Shanghai Ru Xia New Material da kowace masana'antar petrochemical suka haɓaka don buƙatu daban-daban a sassa daban-daban na thermoforming. Masana'antun samfuran thermoforming na ƙasa suna yaɗuwa sosai, yawan masana'antu yana da ƙasa, akwai kamfanoni kaɗan da suka wuce girman, kuma buƙatar samfuran ƙasa yana da bambance-bambance, kuma masana'antun petrochemical suna da nasu tsare-tsaren don tsara samarwa, don haka har yanzu akwai wasu matsaloli don daidaitawa da kyau tare da sama da ƙasa, amma alkiblar ci gaban masana'antar thermoforming ita ce yin samfuran ƙasa daban-daban a gefe ɗaya, da kuma amfani da kayan musamman don samarwa a gefe guda, don inganta ingancin samfura da inganta daidaiton ingancin samfura. Ci gaba da amfani da kayan musamman don thermoforming har yanzu yana da kyau.
