Ukwandiswa kwe-thermal kunye nokunciphisa kufuneka kube yimpembelelo yeqondo lokushisa kwindonga yonke.Ubushushu buchaphazela ngokuthe ngqo ukuncipha, ngakumbi kwi-PVC eqinile kunye nokuncipha.I-shrinkage ye-PVC ebunjiweyo malunga ne-0.1-0.5%, kunye nokwandiswa kwe-thermal kunye nokushisa kwe-contraction yi-70 ° C.Ngamanye amazwi, la mawaka amathathu angasentla asekelwe koku.
Nangona kunjalo, sinokuyihoya into yokuba udonga oludibeneyo luhlobo olutsha lwezinto ezidibeneyo kunye nezixhobo ezininzi ezahlukeneyo, ezifana ne-bamboo powder, i-fiber fiber kunye ne-calcium powder, kunye nezixhobo ezifanelekileyo zokulungisa kunye noxinzelelo olushushu.Ukuba imathiriyeli ekrwada iza kudityaniswa kunye, kufuneka imelane namaqondo obushushu aphezulu.Ngokutsho kophando, ukushisa ngexesha lenkqubo yokucinezela kunokufikelela kwii-130 degrees.Idatha efanelekileyo: Ukwandiswa kwe-thermal kunye nokushisa kwe-contraction ye-PVC yi-70 ° C, kodwa ukushisa kwangaphakathi ngokuqhelekileyo kunzima ukudlula i-45 degrees, kwaye kunzima ukufikelela kwiqondo lokushisa lokwandiswa kwe-thermal kunye nokunciphisa.Kunokuthiwa akufuneki sikhathazeke.
Ukongezelela, inani le-calcium powder kunye ne-powder yokhuni kwindonga edibeneyo nayo yinto echaphazela ukusebenza kwodonga oludibeneyo.Ukongeza ekuphuculeni ukusebenza kwodonga lwe-monolithic ukusuka ekubunjweni, isakhiwo esincinciweyo okanye esine-porous esinemingxuma esetyenziswa ngoku kwindonga ye-monolithic ngokwayo nayo iyindlela yokulwa nokwandisa.
Ukusebenza kwemveliso kufuneka kuthathelwe ingqalelo ngokupheleleyo, kungekhona ekusebenzeni kwezinto ezithile eziluhlaza.Ngoko ke, sifanele siluphathe ngokuchanekileyo oko kufane kubizwe ngokuba bubungqina bokuva.Okwangoku, imboni yodonga oludibeneyo luye lwamkelwa ngokuthe ngcembe luluntu.Kakade ke, oontanga abaninzi baya kulwa nalo ngezinye iindlela.Logama nje iyinyani, iya kusonjululwa ngokwendalo.
