Mphamvu yomangirira ya makatoni a malata imatanthawuza mphamvu yayikulu yolekanitsa yomwe pepala lapamwamba, pepala lokhalamo kapena pepala lapakati ndi nsonga yamalata zimatha kupirira pambuyo poti makatoni amalata amangidwa. GB/T6544-2008 Zowonjezera B zimafotokoza kuti zomatira mphamvu ndi mphamvu yofunika kulekanitsa unit chitoliro kutalika corrugated makatoni pansi pa mikhalidwe yoyesedwa. Imadziwikanso kuti mphamvu ya peel, yofotokozedwa mu Newtons pa mita (Leng) (N/m). Ndi kuchuluka kwakuthupi komwe kumawonetsa kulumikizidwa kwamakatoni, ndipo ndi chimodzi mwazofunikira zaukadaulo pakuwunika momwe mabokosi amalata alili. Kulumikizana kwabwino kumatha kupititsa patsogolo mphamvu zopondereza, mphamvu zopondereza m'mphepete, kulimba kwapang'onopang'ono ndi zizindikiro zina zamabokosi a malata. Choncho, kuyesa kolondola kwa mphamvu zomangirira kwakhala gawo lofunika kwambiri la kuyang'anitsitsa kwabwino kwa mabokosi a corrugated, ndipo m'pofunika kutsindika izi, kuti muwonetsetse chigamulo cholondola ngati khalidwe la mabokosi a corrugated ndi oyenerera kapena ayi.
Mfundo yoyesera mphamvu yamphamvu yamakatoni ndi kuyika chowonjezera chooneka ngati singano pakati pa makatoni okhala ndi malata ndi pepala (lamkati) lachitsanzo (kapena pakati pa makatoni omata ndi makatoni apakati), ndikusindikiza chowonjezera chonga singano. anayikidwa ndi chitsanzo. , ipangitseni kuyenda molingana kufikira italekanitsidwa ndi gawo lopatukana. Panthawiyi, mphamvu yolekanitsa yochuluka yomwe nsonga yamalata ndi pepala la nkhope kapena nsonga yamalata ndi pepala lachitsulo ndi pepala lalikulu zimaphatikizidwa ndikuwerengedwa ndi chilinganizo, chomwe ndi mphamvu ya mgwirizano. Mphamvu yamphamvu yomwe imagwiritsidwa ntchito imapangidwa poyika ma seti apamwamba ndi apansi a ndodo zamalata, kotero kuyesera kumeneku kumatchedwanso pin bonding test test. Chida chomwe chimagwiritsidwa ntchito ndi choyesa mphamvu chokakamiza, chomwe chidzakwaniritse zofunikira zaukadaulo woyesa mphamvu zomwe zafotokozedwa mu GB/T6546. Chipangizo chowerengera chikuyenera kutsatira chodula ndi zofunikira zomwe zafotokozedwa mu GB/T6546. Chomangiracho chimapangidwa ndi kumtunda kwa cholumikizira ndi gawo lapansi la cholumikizira, ndipo ndi chipangizo chomwe chimagwiritsa ntchito kukakamiza kofananira ku gawo lililonse lomatira lachitsanzo. Chigawo chilichonse cha cholumikizira chimakhala ndi chidutswa chamtundu wa pini ndi chidutswa chothandizira chomwe chimayikidwa pakati pa malo a makatoni a malata, ndipo kupatuka kwa kufanana pakati pa chidutswa cha pini ndi chidutswa chothandizira kuyenera kukhala kosakwana 1%.
Njira yoyesera ya mphamvu zomatira: Chitani mayesowo molingana ndi zofunikira za Zakumapeto B "Kutsimikiza kwa Kulimba kwa Makatoni a Corrugated Cardboard" mu standard standard GB/T 6544-2008. Zitsanzo za zitsanzo ziyenera kuchitidwa molingana ndi GB / T 450. Kusamalira ndi kuyesa zitsanzo ndi zochitika zachilengedwe zidzachitidwa molingana ndi zofunikira za GB / T 10739, ndipo kutentha ndi chinyezi zidzatsimikiziridwa mosamalitsa. Kukonzekera kwa chitsanzocho kuyenera kudula makatoni 10 a malata, kapena makatoni 20 okhala ndi malata awiri kapena makatoni 30 a malata atatu (25 ± 0.5) mm × (100 ± 1) mamilimita kuchokera pa chitsanzo, ndipo njira yamalata iyenera kukhala yofanana ndi njira yachidule ya mbali. Zosasintha. Pakuyesa, choyamba ikani chitsanzo kuti chiyesedwe muzowonjezera, ikani chowonjezera chofanana ndi singano ndi mizere iwiri ya ndodo zachitsulo pakati pa pepala pamwamba ndi pepala lalikulu la chitsanzo, ndikugwirizanitsa ndime yothandizira, kusamala kuti musawononge. chitsanzo, monga momwe chithunzi chili pansipa. Onetsani. Kenako ikani pakati pa mbale yapansi ya kompresa. Yambitsani kompresa ndikusindikiza cholumikizira ndi chitsanzo pa liwiro la (12.5 ± 2.5) mm/min mpaka nsonga ndi pepala lakumaso (kapena pepala lapakati / lapakati) zisiyanitsidwe. Lembani mphamvu yowonjezereka yomwe yawonetsedwa ku 1N yapafupi. Kupatukana komwe kukuwonetsedwa kumanja mu chithunzi chomwe chili pansipa ndikulekanitsa pepala lamalata ndi pepala lokhalamo. Zokwanira 7 za singano zimayikidwa, kulekanitsa bwino ma corrugations 6. Pa makatoni a malata amodzi, mphamvu yolekanitsa ya pepala lapamwamba ndi pepala lamalata, ndi pepala lamalata ndi pepala lokhalamo liyenera kuyesedwa kasanu motsatana, ndipo nthawi zonse 10; Mphamvu yolekanitsa ya mapepala, mapepala apakati ndi mapepala a corrugated 2, mapepala a corrugated 2 ndi mapepala opangira mapepala amayesedwa ka 5 nthawi iliyonse, nthawi zonse 20; makatoni a malata atatu ayenera kuyezedwa nthawi 30 pamodzi. Kuwerengera mtengo wapakati wa mphamvu kulekana kwa wosanjikiza aliyense zomatira, ndiye kuwerengera mphamvu zomatira aliyense zomatira wosanjikiza, ndipo potsiriza kutenga mtengo osachepera a zomatira mphamvu ya aliyense zomatira wosanjikiza monga zomatira mphamvu ya corrugated bolodi, ndi kusunga zotsatira. ku ziwerengero zitatu zazikulu. .
