Nyob rau hauv lub tsheb suab, muaj ntau hom ntawm cov neeg hais lus, thiab lub suab ntawm txhua tus neeg hais lus hom txawv heev, uas yog ze ze rau qhov sib txawv craftsmanship thiab cov ntaub ntawv ntawm tus hais lus diaphragm. Cov ntaub ntawv tshaj plaws rau horn diaphragm yog: ntawv tais, yas diaphragm (feem ntau hu ua PP tais), hlau diaphragm, thiab hluavtaws fiber ntau diaphragm. Ntxiv rau cov ntaub ntawv tseem ceeb no, muaj ntau yam khoom siv sib sib zog nqus thiab lub zog siab uas tuaj yeem siv los ua horn diaphragm, xws li silk fiber, wool fiber, graphite fiber, thiab lwm yam. Qee qhov tsim nyog rau kev sau ntawv siab, qee qhov yog tsim rau kev sau ntawv nruab nrab, qee qhov tsim nyog rau kev sau ntawv qis, qee qhov tsim nyog rau kev sau ntawv siab, nruab nrab, thiab qis, txhua tus muaj nws tus yam ntxwv.
Paper phiab, qhov no yog cov khoom qub tshaj plaws.
Cias muab tso, lub pulp ncua kev kawm ntawv yog pub rau hauv lub tais ua ntej tsim zoo li tus mesh pwm, thiab lub pulp yog tso rau nws. Lub pulp, uas tau muab tso rau hauv qhov tsim nyog tuab, yog tom qab ntawd muab tawm thiab qhuav rau kev ua haujlwm tom ntej los ua ib daim ntawv tais diaphragm. Cov muaj pes tsawg leeg ntawm cov ntaub so ntswg, xws li hom thiab ntev ntawm fibers, thiab muaj pes tsawg leeg ntawm fillers, raws li zoo raws li cov txheej txheem ntau lawm thiab post-processing txoj kev ntawm papermaking (xws li cua qhuav los yog kub nias), yuav cuam tshuam cov yam ntxwv ntawm cov ntaub so ntswg. cov khoom kawg thiab ncaj qha cuam tshuam rau lub suab yam ntxwv. Feem ntau hais lus, cov yam ntxwv suab ntawm daim ntawv phiab yog du, ntuj, ci, thiab meej. Vim tias nws muaj cov fibers suav tsis txheeb sib cuam tshuam nrog ib leeg, lub zog xa mus rau hauv nws tuaj yeem nqus tau sai, ua kom zoo damping. Yog li ntawd, lub phiab splitting resonance tshwm sim nyob rau hauv lub high-frequency cheeb tsam ntawm lub suab zaus domain yog tsis pom tseeb, thiab lub cutoff band ntawm yob tawm kuj yog heev du. Qhov no tuaj yeem hais tias yog qhov zoo tshaj plaws vim tias nws tso cai rau kev siv qhov sib faib zaus yooj yim heev yam tsis tas yuav tsum tau txiav tawm ntxiv, thiab kev sib koom ua ke ntawm cov kab ke kuj tseem noj qab nyob zoo. Tsis tas li ntawd, lub rigidity ntawm daim ntawv lub tais yog zoo heev, thiab nws ua tau zoo nyob rau hauv cov ntsiab lus ntawm instantaneous teb thiab mloog zoo. Tsis tas li ntawd, yog tias tsim thiab ua kom zoo, daim ntawv phwj tuaj yeem ua kom hnyav heev, ntau dua 15% sib dua li lub teeb lub diaphragm. Txawm hais tias daim ntawv yog me ntsis hnyav dua li qhov tseeb high-tech hluavtaws fiber ntau cov ntaub ntawv, qhov sib txawv tsis tseem ceeb, ua rau lub suab ntau dua efficiency.
Tau kawg, cov lauj kaub ntawv kuj muaj qhov tsis muaj zog, vim lawv cov yam ntxwv sib txawv nrog cov av noo ib puag ncig. Tom qab nqus dej noo, qhov ntom ntawm daim ntawv nce (ua hnyav dua) thiab nws cov rigidity txo qis (ua softer), yog li cuam tshuam rau nws cov yam ntxwv ntawm lub suab.
Nyob rau hauv xyoo tas los no, ib feem loj ntawm daim ntawv lauj kaub monomers tsim muaj ntau txoj hauv kev txhim kho hauv cheeb tsam no, ua rau cov yam ntxwv ntawm lub lauj kaub ntawv ruaj khov. Cov txheej txheem muaj xws li txheej txheej los yog sau rau ntawm daim ntawv qauv.
