Ngaba i-19mm yePlywood yezoRhwebo siSicombululo kwiingxaki zeWarping kunye nokufuma?

Xa iingcali zokwakha zijongene nemingeni eqhubekayo yokulwa kunye nomonakalo wokufuma kwiiprojekthi zabo, ukhetho lwezinto eziphathekayo luba lubalulekileyo. I-Warping yenzeka xa iimveliso zomthi zifunxa ukufuma ngokungalinganiyo, nto leyo ebangela utshintsho lwe-dimensional olubeka esichengeni isidima sesakhiwo kunye nesibheno sobuhle. Iplywood yesiNtu ihlala isokola nale miba, ngakumbi kwiindawo ezingqongileyo ezinamaqondo ahlukeneyo okufuma okanye ukutyhileka okuthe ngqo kokufuma. Olu hlahlelo lubanzi luphonononga ukuba ngaba 19mm iPlywood yoRhwebo imele esona sisombululo sisiso kwezi ngxaki zolwakhiwo ziqhelekileyo, ukuphonononga iipropati zobunjineli bayo, amandla okumelana nokufuma, kunye nokusebenza kwehlabathi lokwenyani kuzo zonke izicelo ezahlukeneyo.

Ukuqonda iiPropati eziPhambili ze-19mm yePlywood yoRhwebo

ITekhnoloji yoLwakhiwo lweeNqanaba ezininzi eziPhezulu

Isiseko se-19mm yoRhwebo lwePlywood yokwenziwa komsebenzi silele kulwakhiwo olunobunkunkqele olunamaleko amaninzi, olubandakanya iileya ezili-13 okanye ngaphezulu zeveneer ezicwangciswe ngokwepateni ebhendiweyo. Le ndlela yobunjineli idala uzinzo olukhethekileyo olujongana ngqo neenkxalabo zokulwa. Umaleko ngamnye ukhethwe ngocoselelo kwiintlobo zomthi oqinileyo womgangatho ophezulu oquka i-eucalyptus, ipayina, ipoplar, kunye nebirch, kunye necala lenkozo elitshintshana phakathi kweeleya ezimeleneyo. Olu lungelelwaniso lwe-cross-grain lusasaza ngokufanelekileyo amandla oxinzelelo kwiinqwelomoya ezininzi, ukunqanda intshukumo ye-unidirectional eyenza i-warping kwimithi eqinile okanye iimveliso ze-plywood ezingaphantsi. Iinkcukacha zoxinaniso lwe-600-650 kg/m³ ye-19mm yePlywood yoRhwebo iqinisekisa umlinganiselo wokomelela ukuya kubunzima ngelixa ugcina ukusebenza. Olu luhlu loxinaniso lufezekiswa ngolawulo oluchanekileyo lwenkqubo yokulungiselela i-veneer, apho iileya zomntu ngamnye zomiswa ngononophelo kwisiqulatho sokufuma phakathi kwe-8-18% phambi kokuhlanganiswa. Uxinaniso olungaguqukiyo kuyo yonke indawo yolawulo luthintela ukwakheka kwemimandla ebuthathaka enokukhokelela kwimfazwe yendawo okanye i-delamination phantsi koxinzelelo. Iinkqubo zokuvelisa e-Linyi Longterm Wood Industry Co., Ltd. zibandakanya imilinganiselo engqongqo yolawulo lomgangatho ehlola umaleko ngamnye we-veneer iziphene, iqinisekisa kuphela imathiriyeli yepremiyamu enegalelo kuzinzo lwemveliso yokugqibela.

Iinkqubo zokuncamathelisa ukufuma

Itekhnoloji yokuncamathelisa esetyenziswa kwi 19mm iPlywood yoRhwebo imveliso imele ukuqhubela phambili okubalulekileyo kwiindlela zokudibanisa zemveli. Iinkqubo zokubambelela ze-MR (i-Moisture-Resistant) kunye ne-WBP (iMozulu kunye nokuBilisa) zenziwe ngokukodwa ukuze kugcinwe ingqibelelo yebhondi phantsi kweemeko zokufuma ezinzima. Ezi zibophelelo ezisekelwe kwi-phenolic zenza iibhondi zeekhemikhali ezihlala zizinzile nangona zibonakaliswe kumswakama ophezulu, ukuguquka kweqondo lokushisa, okanye ukudibanisa ngqo namanzi. I-adhesive ingena ngokunzulu kwisakhiwo se-veneer, idala i-interlock yomatshini ehambelana nokudibanisa kweekhemikhali ukwenzela ukuhlala ixesha elide. Izatifikethi zokusingqongileyo ezibandakanya ukuhlelwa kwe-E1 kunye ne-E0 ye-formaldehyde ziqinisekisa ukuba i-19mm yePlywood yoRhwebo ihlangabezana nemigangatho engqongqo yokukhutshwa ngaphandle kokuphazamisa ukuxhathisa ukufuma. I-adhesives eco-friendly esetyenziselwa imveliso isusa iikhompawundi ezinobungozi eziguquguqukayo ngelixa zigcina amandla aphezulu okudibanisa. Oku kudityaniswa koxanduva lokusingqongileyo kunye nokugqwesa kokusebenza kwenza ukuba imveliso ifaneleke kwizicelo zangaphakathi apho umgangatho womoya ubaluleke kakhulu, ngelixa unikezela ukuchasana kokufuma okufunekayo kwiindawo zokwakha ezifunayo.

Uzinzo lweDimensional Phantsi kweeMeko eziguquguqukayo

Uvavanyo olubanzi lubonisa ukuba i-19mm yePlywood yoRhwebo igcina uzinzo olukhethekileyo kuluhlu olubanzi lweemeko zokusingqongileyo.
