Processing na takardar

PVC kumfa takardar bukatar kammala gefuna. Domin wadannan dalilai, za ka iya amfani da jirgin sama, sandpaper ko wasu kayan aiki amfani ga sawing itace ko roba gefuna. Idan kayan shigarsu m tsauri kaya magudi iya rataye ga abin da ya faru da gãfartawa ko fasa. PVC takardar ciwon kauri ba fiye da 3 mm, za a iya yanka da talakawa wuka.

Stamping PVC roba

Yadda ya dace da punching shi ne dogara da dalilai da dama:

• takardar kauri - takardar kauri of 3 mm ake ƙulli sauƙi. Idan na musamman kayan aiki da kuma ta dace dabaru aka yi amfani, sauki siffofi iya niƙe daga PVC kauri daga 4 zuwa 6 mm. Lura da cewa gefuna da takardar haka a dan kadan taso keya.
• takardar zazzabi - tare da kadan kayan preheating punching ingancin ne inganta;
• kayan aiki don stamping - dace kayan aiki ga stamping kwali da kuma sauran foams.
• ruwa kwana - alamomin punching ingancin ne wuri na ruwa a wani kwana na 30 °.

hot lankwasawa

Domin wadannan dalilai, yi amfani da wani misali kayan aiki ga lankwasawa thermoplastics. M lankwasawa dogara a kan wani uniform zafin jiki rarraba da qaddara m dumama zone. A mafi kyau duka zazzabi matakin - daga 115 zuwa 130 ° C. Idan zafin jiki ne mafi girma daga kayyade matsakaicin, akwai wani babban Yiwuwar samuwar fasa da tsãgewar ƙwãyar PVC salula tsarin. Wannan ya faru sau da yawa a lokacin da mafi lankwasawa thicker zanen gado. A hali na kasa da dumama da kayan za a fuskanci tsananin gajiya, da yiwu dawo da asali jihar.

Lokacin da lankwashewa foams gefe dumama ne nasara ne kawai don wani lokaci, don haka da lankwasawa radius iya zama gani unsatisfactory. A wannan yanayin, a ciki gefen da takardar da aka amfani da su V-dimbin yawa incision. A wannan alamomin ne kam samu samfurin har sanyi abu.

Bonding PVC zanen gado

PVC kumfa yi lends kanta zuwa daban-daban iri m bonding wakili. Idan ya zama dole to manne da zanen gado da juna, za mu iya amfani da wani m ga rushe sanyi waldi ko amsawa (na biyu) manne. Domin da bonding wadanda ba porous da kuma wadanda ba absorbent kayan dace da wadannan iri manne:
